This is a basic handle that I made for the M4 tap I needed to mod the bearing blocks on my Maker Select in order to install Thorped's Wanhao fan duct.
There is a hole if you want to add a setscrew. It should allow for an M4 screw, though you may want to use the tap beforehand, to reduce the chance of splitting the layers. You'll probably want a shorter screw than the one I have, which is 16mm. 7-10 mm would probably work best. :)
Infill and material is up to you; I used 25% and PETG.
