I created these models so that I can design fixtures for making them out of wood. These models are fully functional and can be used to print working forearms for the 880, 922, 822, and another model Daisy that has compatible forearms. I also designed a set to work for the 1977. I added the models to Thingiverse.

There are lots of possibilities with printing these forearms. Printing with wood filament and staining then finishing is pretty cool.  The forearm below was printed with AMOLEN Dark Wood Walnut PLA Filament then lightly sanded with 120 grit sand paper and wiped with Minwax Jacobean stain.

Even if you don't have access to a 3D printer you can order parts from printing services such as CraftCloud
