just a cap that goes on the motor pulley/gear.
The pulleys on mine were 13mm. I made the inner hole of model 13.05mm with 0.8mm walls.On mine it was tight enough to fit over the pulley. Taking it over may be difficult tho'.
I was able to print it dual color by pausing and swapping the filament.
V2
- Increased the tolerances
- Added a simmilar part for the other pulley. Unless you have really thin double sided tape, you may use a tiny drop of silicone sealant, or even superglue only in the middle of the part that touches the axle (not recommended at it might affect the seal, or the vapors might get underneath it)
- Added the f3d file for both files
V3
- Added a flat version of the cap used for the big pulley
- Modified the cap for the small pulley to help centering it easier
- Some small chamfers here and there to help inserting and centering them easier
