A8 Extruder button

This is not the first thing I made, but it should be something useful and not too dependant on your machine calibration. Its a simple button to fit over the M3 bolt which forms part of the extruder on the Anet-A8. I got fed up of bruising my thumb whilst I was trying to adjust the filiment in the extruder.

Needs some infill, doesn't need a raft or brim. Shouldn't be too fussy about cooling (although my first attempt was damaged by contact with a custom fan shroud).

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/20xOcVnzDiB
