Bed Levelling Thumbwheel for Wanhao Duplicator i3

thingiverse

Update 27/11/16: Made bottom thinner so more of the screw can be used. Update: Made holes slightly smaller so the fit is tighter. This is a remix of the Bed Level FingerKnob by Webberen: http://www.thingiverse.com/thing:1032666 I found that the round hole was too small, and the hex hole was too big so the nut would slip. So I made my own. Might have been the dimensional accuracy on my printer. This version also has a larger diameter and is thicker, similar in size to the stock metal thumbwheels that come with the v2.1. It was designed to use an M3 nyloc so the hole for the nut is also deeper so it sits further inside the thumbwheel. I printed them with 1.2 mm top/bottom shells and 2 mm walls, but you could probably get away with 1.2 mm walls also.
