Skull piston cavity molds

thingiverse

The skull piston key chain (https://www.thingiverse.com/thing:2055033) is so cool I had to make one and try the cold casting method. I thought it would be easier to print the cavity for the silicone mold, than to make it by hand. I scaled it down to 66% to get a smaller version. I broke it at the base of the skull after about 3 hours. I would suggest scaling it back up. Anyway here are the cavity molds if you want to print them. If you want the piston itself please see the original maker, "skull piston" by reflexpnt.
