Recently I have been preparing the body parts for printing and assembly. Adding tolerances (gaps between parts) , beveling (removing square edges for cleaner prints) and adding little pegs with holes so the whole thing can be assembled with the same sized small screws.

I'm just waiting on some red and blue PLA filament to arrive to print some test parts and check all my guesses.

As we are creating something that will interact with food we need to be food safe. PLA is considered food safe (It's made from corn starch) and we will use food-safe petrolium jelly as a lubricant in all the joints.
