This was my test mold for oogoo tests
(oogoo is silicone caulking and cornstarch mixed 50/50 or less starch )
if you print it and cast, there are no allignment
holes, so you need to use a flat surface to line
the sides up.
It cast pretty well and was a good mold to learn some about oogoo casting in ABS.
not a derivative but props to jasonwebb for inspiration with this thing: thingiverse.com/thing:31581
print in ABS for the molds, I have not tested oogoo in PLA.
I used a 10% infill and the finer a slice the better.
Also i have found that acetone wash on the mold cavity
makes a smooth surface which looks great on the castings.
casting process: fast cast:
mix your oogoo and pack the mold halves
place copper wire in the center of the arms and legs
for the arms i make one wire hand to hand thru the torso.
to center the wire place a few beads on the ends and middle of the limbs
(size of beads depend on the mold size and wire size)
for the legs again go foot to foot (make a extension into the body a bit to help
anchor the wire)
again beads help keep the wire centered.
once the packed halves are ready to be merged
c-clamps to squeeze the 2 sides together and hold it for the curing period.
I have made casts using a thin "painting" of straight silicone
caulking that i let harden for 24 hours, and then follow the fast cast procedure.
this ensures a better surface finish on the casting.
make sure that the thin coat is thin!
This is great if you make a glow in the dark outer coating! (using glow pigment)
