Dual split shaft collars are mechanical clamps used to secure components—like bearings, pulleys, or gears—onto a shaft.
This 3D printed double split shaft collar utilizes m3 nuts and screws (m3x12) (https://amzn.to/435tkve, aff.) for reliable rotation. The two splits are both 3D printed. The original model is designed for a 20cm x 20cm square shaft. Feel free to modify the parametric Fusion design file or just DM me for help.
Print settings:
Supports: No
Brim: No
Additional Settings: PETG (any rigid material is fine), 3 perimeters, 15% infill, 0.2mm layer height
- 3 perimeters is semi-solid
- You can make it weaker, but since the part is overall pretty small, I found that to be unnecessary.
Of course, this is a 3D printed shaft collar is intended for minimal load/speeds. It is intended for prototypes and proof-of-concepts. So please don't put it in a transmission system of a car or Spaceship ;)
