Rough copy of an allen t handle that came with a set (this thing: https://www.amazon.com/Numkuda-Internal-Hexagonal-Auxiliary-Labor-saving/dp/B07K33X7SW). A little longer than the original

Requires and m3*20+mm screw and an m3 nylock. The nylock has to be shoved all the way down the longer part. Then basically just tighten the screw all the way and back off until the smaller part turns again.

Update to fix and add sketchup files
