Alright I’ve finished up the motor-side of the bumper. It’s essentially the other half to the previous bumper, I plan on printing both to protect the purrrty anodized aluminum from AT boogers.
Notes
- Clears 7" (175mm) tires to stand the board up on the motor mounts
- 63mm diameter recess in bumper for motors (reach out if you need larger)
- Be sure to print the correct bumpers for your drives: V1 or V2; V2 has M3 lid screws
Fitment
I can’t really comment on fitment yet as I’m still printing V1 bumpers (I unknowingly made V2 bumpers first, lucky you guys). I do have a full set of V2 bumpers and they fit very well on my V1 drives. The differences are very slight so I suspect they should fit fine on V2 drives.

Known Issues / Future Work
- The lid bolts compress the bumpers; use washers or wait for a small/thin shim plate I’ll release after testing (currently printing). Your current screws should be long enough.
- Back bumper design isn’t ideal if you aren’t using both bumpers
- Easily fixed; just needs to be cut shorter (ideally in your slicer)
- I’ll remix another STL with “shortened” back-only bumpers
- You may need to scale slightly depending on your printer/filament
- Once I test fit my V1 bumpers I may adjust tolerances
- I need to release some step/f3d files for you folks to remix at will
Free bumpers
Since I printed a full set of V2 bumpers I have a set to give away if you cover shipping; PM me.
