I designed this grip for the handle of the Inmotion V12 electric unicycle because I lost the original one.

For safety I drilled a 6mm hole in the metal handle and fastened it with a screw. The screw needs to be 45mm long. M4x45mm

Although in my case I put an M5x45mm one because I couldn't find M4's that long.

UPDATE (2024/04/28) I have added the same files but with a 5mm diameter hole and renamed the originals indicating that the hole is 4mm. This name change is to make it easier to choose the file to download and the appropriate through bolt in each case. The differences between v3 and v3.1 are minimal (I have added images showing details of each version) and both have a file with a 4mm and a 5mm hole.

The material is TPU 95A so it won't break in possible drops or impacts.
