I got a request a while back for this model. It is replacement parts for a wood planer, don't know what model.

It is designed in a way so it can be separated if something brakes.

There are 5 parts (3 FDM prints and 2 MSLA):

1. Small gear - it goes into the pulley. I printed it with PAHT-CF from Bambu and PA like nylon from sunlu.
2. Pulley - printed from PETG
3. Chain gear - because of complex geometry it is printed with PA like nylon
4. Big gear - printed with PETG

Also, I used 2 PCM 101212 E bushing for Small gear part, because it kept breaking from heat caused by traction.
