Drive belt for Singer Featherweight 221/222
thingiverse
Print using TPU or similar flexible filament, use your favourite settings or defaults and of course a color of your own choice. I've used 95A hardness TPU. Support not needed. Belt has been tested on my 1949 Singer 221K, should work with other Featherweights as well. Let me know if you have issues.The design is based on measurements on the original drive belt on my machine (old and new belt in picture). Length also cross checked with new belts that are 17 1/2 inches long. I did reduce the length by 2 mm to allow for a bit more adjustment when mounting on the machine.
