This is a rotational casting machine I made so that I could print a mold and make hollow copies of the object in that mold with resin. It works just fine and there are 2 different versions you can download here.

One is fully automatic and requires a motor, controller, and power supply. If you don't want to go with power there is also a manual option with a hand crank. If you want power do not print the stl's ending in MANUAL. The same goes for if you want the hand crank do not print stl's ending in POWER.

Here is the list of additional parts you will need.
