I decided to make this arm model for a larger project i am working on. currently, it's only made for medium to large size arm. I printed the hinge in one piece and the other pieces in vase mode, altho I would recommend most people print the hinge pieces separately. WIP, will make a more printable all in one file later
print without supports, turn on detect thin walls for the custom design in support on the hinge pieces. arm covers printed in vase mode(duh).
file down the support side of the hinge rings, add grease to greaseport on bearings. glue bearings in vases
