A
And
I
have
a
background
in
chemical
engineering,
because
Bachelor
of
engineering,
machine
development
plus
I
worked
like
6
years
7
years
and
designing
components
was
you
know,
I
was
auto
cad
and
in
Ventura.
So
with
all
the
SDS
finance
I
have
a
little
problem
because
my
vendor
don't
like
them
at
all,
so
I
have
to
use
different
parts
to
fill
them
up
so
get
them.
They
get
them
follow
them.
A
What's
my
biggest
concern
is
I
see
that
from
an
engineering
point
of
view,
and
that's
also
a
little
colonisation
and
I
had
a
lunch
break,
it
will
be
cool
to
have
the
engineering
point
of
view
integrated
in
more
integrated
in
enables.
So,
for
example,
I
did
some
modifications
with
the
arm,
and
it
is
done
by
a
program
that
we
have
an
enable,
but
I
cannot
get
the
parts
in
it.
A
So
I
take
the
long
way
around
I
just
use
the
program
that
we
have
to
scale
them
up
and
then
I
will
use
my
modifications
for
an
inventor
and
I
would
sketch
them
over
that,
so
that
I
can
just
use
the
whole
education.
So
that
being
said,
if
you
take
from
an
engineering
point
of
view,
it
would
be
coolest
there's
one
major
database
where
you
have
all
the
folders,
where
you
can
say:
ok,
there's
just
immersion
aid,
this
is
version
B.
A
This
is
version
C
and
the
extra
version
is
just
and
the
main
stage
so
that
you
can
go
on
from
there.
But
now
the
point
is
because
I
come
from
big
companies.
It
is
not
good.
If
everyone
can
access
this
and
change
them,
it
would
be
good
if
this
one
person
to
person
responsible
to
adding
them
and
pulling
them
in
and
the
other
one
can
just
copy
them
and
download
them,
because
if
you
have
Jeremy
saying
I,
don't
know
the
same
like
in
English.
If
you
have
several
coups,
then
they
will
just.
A
Also,
my
company
is
a
big
Japanese
company
that
I
work
with.
We
have
lots
of
guys
that
can
use
the
tools
or
there
are
only
two
guys
allowed
to
change
them
and
put
them
in
their
archives,
because
it's
a
lot
of
guys
doing
this.
They
mess
up.
And
if
you
don't
track
record
of
what
you're
doing,
then
you
you're
totally
confused
so
whatever
in
said.
The
first
thing
I
did
was
I
took
a.
B
A
The
Phoenix
in
Phoenix
and
is
nice
and
doesn't
actually
this
product
that
all
of
the
kids
in
jewelry,
like
some
like
rough
rough
terrain,
but
this
one
one
but
they
like
and
then
I,
saw
the
videos
and
saw
that
most
of
the
guys
drew
it
by
hand.
So
they
can
perform
it
and
then
they
can
perform
it
by
hand.
And
for
me
it.
B
A
This
you
get.
If
you
do
to
two
gauntlets,
they
look
totally
different,
and
that
is
what
bothers
me
I
want
to.
If
I
want
to
create
something,
it
should
always
look
the
same.
So
I
started
doing.
Think
about
that.
How
much
do
you
need
to
really
accomplish
similar
design
and
just
do
it
one
time,
and
then
you
print
it
another
time.
So
I
came
up
with
forming
tools
for,
for
example,
forming
the
gauntlet.
A
I
just
need
two
tools
and
performing
the
mentally
I
have
another
tool
to
just
push
it
in
there
and
to
make
it
accurate
and
for
plastic
bag.
I
label
them
with
the
precision
lines,
and
then
I
can
just
put
it
away
and
next
time,
I
have
another
kid
same
size.
It
works
fine
and
the
fun
is
second
days
I
found
out
that
a
guy
like
da
Vinci
was
right,
yeah.
A
Okay,
that's
not
110
percent
light
from
the
little
girl,
it's
190
percent,
so,
okay,
you're
an
engineer
you're
a
little
bit
lazy,
so
just
gave
it
up
for
110
to
109
T
and
it
fits
perfect
and
that's
what
I
find
out
the
difference
when,
when
you
design
these
foreign
tools
is
really
not
that
much.
If
you
have
this
size
and
width,
it's
probably
safe
from
the
people,
they
are
just
three
or
four
people
that
I
get
to
know.
A
A
Scale
it
like
I,
said
if
the
girl
that
this
110
percent
hand
and
-1
and
90
I
just
can't
hurt
40
tools
up
to
190,
use
them
and
it
fits
perfect
and
I.
Just
said
like
in
the
exhibitions,
I
had
three
or
four
guys
that
had
this
bigger
on
her
arms,
they
didn't
fit
the
current
profile,
but
usually
all
of
them
fit
the
profile
s.
It
was
quite
nice
from
that
out,
so
I
have
these
files
as
well.
A
So
right
now,
with
the
Netherlands
I
start
some
like
in
Dropbox
and
then
I
give
them
the
X
or
heads,
and
they
are
I've
already
created
it
like
this
I'm,
the
master
I
can
and
them
in
and
if
they
have
fights,
I
will
add
them
in
and
they
can
just
read
and
comment
download
them.
So
it
will
not
confront
and
get
confused.
Usually
I
tell
my
colleague
co-workers
that
I
do
see
ad
work
on
a
professional
level.
Don't
just
pull
files.
A
India
also
add
a
text
file
where
you
say
what
you've
done
so
that
no
one
gets
confused.
So
we
didn't
have
a
track
record
because
you
have
to
fight
us,
but
they
turned
it,
confuse
the
people
all
the
time
and
then
comes
materialise,
nation
for
emergencies,
I,
analyzed,
Phoenix
and
I.
Take
it
from
stretch,
because
my
professor
said
this
is
a
good
topic,
but
just
figure
out
something
that
you
want
to
test
it,
and
so
I
figured
out.
Okay
I
have
to
test
the
nylon
strings.
I
have
to
test
the
knots
when
a
knots.
A
The
next
step
is
to
land
slower,
because
that
is
the
knots
are
connected
with
the
fingers.
So
I
have
to
test
the
PLA
as
well
and
then
for
me,
critical
part.
Was
this
part
here
because
yeah
you
have
a
connection
of
having
PLA
connected
with
screws,
so
I
build
the
DISA,
so
basically,
I
did
ten
tests.
On
this
hand,
each
test
was
done
five
times
so
have
a
beverage
when
I
killed.
A
Do
it
just
like
on
an
axle
scale
and
first
thing:
I
did
test
the
five
times
the
strings
on
Jun
room
temperature,
then
I,
let
them
age
five
times.
I
put
them
for
I
think
one
hour
at
60
degrees
in
an
oven
and
then
I
tested
them
afterwards.
So,
like
aging
process,
if
you
have
usual
plastic
aging
processes,
also
and
Ageing
Kevin
just
applies
heat
over
long
period
of
time.
So
as
it
is,
it
is
hadith.
A
B
A
To
water
them
the
worst
stretch
to
get
so
the
last
test
was
done
and
say
there
was
60
degrees,
active,
so
I
for
every
test.
I,
measured
the
room
temperature
and
the
middle
measure.
The
humidity
and
record
this,
and
for
the
active
test.
I
have
two
three
different
kind
of
temperature
measurement
systems,
so
that
I
can
apply
it
with
a
motel
or
temperature
on
the
string
at
310
meters
to.
B
A
The
temperature
and
the
stretching
is,
you
can
get
nearly
every
material
like
and
they
didn't
get
there.
Nearly
every
Imam,
but
for
nylon
strings
is
nearly
impossible.
It's
like
they
keep
it
a
secret
like
the
tire
people
will
never
tell
you
what's
in
them,
because
you
can
get
the
nylon
strings
really
stronger.
If
you
add
additional
materials
or
additional
classes
or
additional
chemicals,
and
they
get
stronger,
they
have
different
versions
of
what
they
can
last
and
you
can
just
get
the
basic
pH
66
and
that's
really
strange.
But
what
was
interesting.
A
I
did
tests
that
were,
let's
say,
picture
based,
so
I
had
a
testing
facility
and
I
did
not
test
it
with
machines
like
the
non
brothers
tested
like
you,
do
want
to
make
it
reliable,
because
the
people
that
these
tests
will
have
look
at
our
families
and
my
special
task
force
make
a
stretch
between
doing
a
technical
research.
That
Latin
death
is
a
good
baby
for
that
short
eases
and
make
it
reliable
for
people
and.
B
A
Later
on,
I
will
tell
you
why
this
was
the
best
idea
that
I've
ever
had
so
my
test
was
basically
I.
Had
a
camera
set
up
and
I
had,
for
example,
the
nylon
string,
I
made
two
lines
on
that
and
without
applying
force,
I
take
the
first
picture
and
then
I
apply
500
gram
of
weight.
Take
another
picture,
another
photograph
take
another
break
and
all
this
added
up
till
the
night
on
report
and
this
most
of
all
test
and
then
I
could
say.
A
Okay
was
this
kind
of
pressure
or
this
kind
of
force
I
have
this
gun
blank,
so
I
could
make
a
stress,
strain
diagram
from
that,
and
the
funny
part
was
was
not
one
I
could
not
I,
don't
have
so
much
data
because
they
don't
tell
you
exactly
how
much
how
much
a
new
parameter
is,
but
with
people
a
it
was
the
data
from
auto
maker
board.
They
put.
C
A
That
was
64,
65
point
7,
Newton
per
square
millimeter
and
my
result
over
the
five
tests
with
my
pulling
string
was
not
65.
It
was
sixty
six
point
zero.
Two
and
my
professor
said
you
know
this
is
not
a
Dean
test
that
you're
doing
but
you're
nearly
as
accurate
as
and
Dean
test,
so
you
can
go
on
with
them.
So
now,
why
did
I
do
with
tests
like
this?
After
that?
A
You
know
you
have
to
trust
us
and
then
it's
all
so
my
words,
but
I
need
a
test
that
they
can
really
rely
on.
I
said
you
know:
I
have
the
string.
I
have
get
in
and
I
put
in
really
salt,
because
the
bit
later
on
the
basket
will
drop
on
the
floor.
And
then,
if
you
have
something
that
you
can
just
shovel
back
in
that's
better
than
just
water
or
so,
but.
A
Say
you
know
the
D
test
is
this
is
the
result
from
the
D
test
and
I'm
just
0.3
Newton
per
square
millimeter
beside
that,
so
that
helps
a
lot.
That
being
said,
comes
to
the
development
part
of
all
this,
because
every
printed
object
has
also
may
not
move
one
of
the
reasons
that
I
found
interesting
in
the
presentations
before,
especially
if
you
print
something
they
don't
have
the
same
email
in
every
direction,
because
you
always
get
two
emails,
the
TD
version
and
the
Handy
version.
Juanes
hi.
A
Everyone
is
lower,
what's
the
reasonable,
because
if
you
have
to
print
Direction
like
this
and
you
pull
the
strings
like
this,
it
has
more
strengths
and
will
retain
more
strengths.
Then,
if
you
have
two
layers
like
this,
and
then
you
pulled
layers
out
like
this,
that
was
the
reason
when
I
did
the
bird
date
of
the
bird.
A
A
A
I
tend
with
the
idea
of
making
a
movable
feet,
and
the
problem
was
when
he
stepped
on
his
prey
with
25
kilogram.
Wait
like
four
to
five
kilograms,
so
he
treads
on
a
prey
like
525
kilogram.
I
cannot
print
this
part
in
one
piece
because
they
wanted
to
ever.
Look
like
it
roughly,
like
the
fields
will
do
of
the
bird
I
could
not
print
it
out
right
like
this,
because
then
the
letters
would
be
like
this,
and
this
here
this
part
is
the
movable
part.
A
So
as
soon
as
it
moves
and
he's
tries
to
step
it
through
a
break,
so
I
had
to
print
the
middle
part,
the
center
part
laying
down
so
that
the
lands
will
not
be
correct.
So
this
will,
with
stain
all
the
stepping
and
the
bird
just
stepped
a
lot
in
the
beginning,
but
there
was
another
issue
about
that
is
I
put
a
lot
of
screws
in
because
he
walks
on
field
and
also
in
the
winter
time
it
was
an
African
bird.
A
A
We
call
that
because
food
was
just
from
the
keepers
and
I
said:
ok,
maybe
the
bird
doesn't
get
care
about
the
food
it
just
needs
to
8
centimeters
music,
like
this
piece
was
missing
and
it
came
up
with
a
good
idea
for
sports
mode,
no
screws
in
it
lighter
like
100,
and
he
works
fine
with
them.
He
still
works.
Fine
with
that,
and
there
comes
the
issue.
I
didn't
expect,
for
example,
this
is
the
lower
leg
of
the
bird
and
that
comes
to
a
ballet.
A
Well,
so
this
little
piece
here
and
after
pins
and
the
first
time
it
broke,
was
here
and
I
was
like
Cathy,
actually
is
just
one
bone,
so
I
reinforced
it
three
times
in
different
sections
until
I
finally
to
make
this
version
work,
it's
a
full
printed
portion
because
there's
really
stronger
and
as
a
little
detail,
everyone
keeps
asking
me
was
this
I
said
this
is
just
for
the
bird
to
keep
it
upright
it's
so
this
one
here
see.
Actually
the
hinge
ordered
once
at
the
elbow
I,
don't
know.
A
What's
that,
call
that
a
bird
let's
say
the
elbow
of
the
bird,
so
it
cannot
twist
at
the
elbows
in
like
here
it
cannot
twist.
So
it
stays
in
position.
That's
just
a
little
detail
of
engineering
trick
when
I
did
a
storage.
It
was
like
a
little
bit
tricky
because
it's
tore
shot
just
like
as
much
of
a
lower
vacuum
is
much
more,
and
this
hinge
is
just
for
a
position
in
right,
so
it
would
not
turn
with
this
kid.
Always
engineering
tricks,
like
the
Storch
always
walks
on
now
was
that
called
concrete.
A
A
So
it's
always
thinking
out
of
the
box,
but
the
main
focus
I
have
is
I,
get
a
lot
of
requests
and
that's
one
thing:
my
clothing
of
a
lot
of
requests
right
now
from
dog
homes,
but
dorks
are
not
as
perfect
as
Birds
I
always
keep
telling
you.
Sometimes
the
dog
almost
come
to
me
and
ask
me
you
know:
can
you
do
my
know?
A
How
can
I
say
how
heavy
is
your
door
and
then
go
like
40
kilogram
study,
not
so
much
because
for
an
engineer
point
of
view,
when
a
dog
just
walks,
it
ate
twice
as
weighed
when
he
starts
running
you
around
3.5
times
as
weight
and
then
comes
to
engineering
I.
Let's
say
the
engineering
feeling
that
you
say:
okay,
I
know
from
indefinitely
hammering
and
all
the
engineering
I
know
all
the
techniques
that
are
available,
but
I
am
limited
in
what
I
can
do
with
it.
A
3D
printer
I
can't
force
this
prosthesis
for
the
dog
to
be
printed
in
plastic,
but
then
it
will
be
really
big
to
just
last
the
other
way.
I
told
them
just
go
to
a
prosthesis
manufacturer.
I
can
do
your
design
and
he
can
get.
He
gets
access
to
see,
Luke,
Alvin
and
all
the
stuff,
and
you
can
make
it
slim
and
nice
and
small,
so
I
always
tell
my
students
and
all
the
stuff
that
they
should
not
force.
A
If
you
just
force
him
to
have
a
big
same
ideas
like
just
to
let
make
it
last
because
we
saw
with
the
African
secretary
bird
it's
now
living
two
years
with
this
prosthesis:
okay,
I
print
them
every
year,
print
em,
a
new
one,
because
it
tears
down
all
the
time
he's
walking.
They
keep
telling
me.
You
know
what
you
did
is
funny,
because
you
could
really
see
different.
The
world
is
growing
up
and
glowing
because
with
more
eager
the
prosthesis
it
was
like
he
didn't
eat.
Well,
it
was
a
little
bit
like
depressed.
A
Sometimes
they
could
get
out
of
the
cage,
and
with
this
he
starts
eating.
Well,
he
runs
around.
Sometimes
it's
just.
They
are
scared
because
they
have
to
slow
him
down,
he
runs
faster
and
they
were
like,
and
even
he
tries
to
hunt
with
this
prosthesis.
Do
you
know
he
steps
on
the
head
of
snake
and
they
have
stopped
snake
that
they
pull
around
and
sometimes
he
just
tries
to
reel
and
then
with
the
other
end,
he
don't
care,
no
more.
She
don't
care,
and
so
that's
a
good
thing.
I
think.
A
Message
is
just
when
you
do
this.
Just
consider
everything
around
you.
You
don't
have
to
engineer
everything
from
scratch.
Yeah
just
go
to
opposite
way
of
doing
like
the
Chinese
and
doing
it
bloody.
If
there
is
something
that
an
idea
that
someone
else
already
invented,
maybe
you
can
implant
it
in
your
system.
C
A
It's
actually
the
point
that
German
and
Germany
and
specially
Europe
is
not
aware
of
all
the
plastics
in
the
sea,
and
with
this
you
can
still
that's
why
I
print
everything
in
pl8,
then
you
can
still
go
on
and
say
you
know
we
are
actually
not
the
reason
for
plus
they're
gonna
see
because
it's
just
by
a
Red
Bull
in
weight.
That's
also
the
reason
why,
when
I
read
remodel
the
fingertips,
I
used
some
like
natural
natural
rubber,
so
that
you
can
say:
oh
it's
all
natural.
A
Also
in
Germany
we
use
neoprene
and
till
the
day
I
had
to
figure
out
the
nice
conversation
with
the
Department
of
Medical
Products
in
Germany,
I,
didn't
know
what
exactly
you
pre
consists
of
and
there's
also
natural,
some
substance
and,
and
the
funny
part
is
to
go
in
the
medical
department.
There
are
two
way
and
two
types
of
neoprene:
that's
one
is
medical
right,
other
ones.
Not
the
difference
is
just
it
is
they
use
a
gas
to
make
it
foam
like
and
for
to
be
medical
grade?
A
They
use
nitrogen,
so
the
bubbles
will
be
filled
up
with
nitrogen
and
for
others
they
just
need
compressed
air
and
the
only
consent
concerned
that
medical
products
have
is.
When
you
use
natural
air,
there
could
be
a
chance
slight
chance
of
in
these
really
tiny
bubbles
is
a
bacterial
farm
growing,
but
effect
on
the
human
body
is
like
that:
you're
getting
red
dot
on
your
skin
at
max.
That's
just
the
point
we
tried
to
do
it
more
like
because
right
now,
jr.
A
OBE
is
really
evolving,
especially
with
the
cars
they
are
so
concerned
about
pollution
and
all
the
stuff.
So
when
you
use
plastic,
that
is
really
like
your
plastic.
Then
they
go
like
plastic
in
disease
and
that's
like
we
are
a
bit
more
aware.
So
I
try
to
do
it
all
like
they
say
the
organic
way
and
so
on,
because
most
of
the
Germans
don't
know
about
PLA,
and
then,
when
I
tell
them,
you
know
in
some
medications,
there's
even
be
laid
inside.
A
Then
they
go
like
wow
and
I
was
like
that's
just
a
point
but
I
think
for
for
further
trials,
especially
when
I
tried
to
test
some
of
the
new
models
from
from
Christian.
So
I
will
just
consider
other
materials
as
well,
because
and
now,
how
much
did
the
appeal,
a
it
will
last
and
just
consider,
but
for
the
kids
and
all
the
other
stuff
I
try
to
be
on
the
natural
side.
So
it's
more
a
very
image
for
enamel
as
well.
