bendybot mold (cerby's crawlers 03)
by cerberus333, published
This is a mold of a accordion limbed robot for casting in oogoo. http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/ I wanted a figure with snake-like arms and legs to bend around things and look cool! I attached the model of the bot as a file if you want to print it as a figure.
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.
the holes thru the corners of the mold halves are for alignment, use a nail or other rod to align the halves when press molding.
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 i use nails in the 4 holes to align the sides. and c-clamps to squeeze the 2 sides together and hold it for the curing period.
fine cast: 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)
