Bed Levelling Thumbwheel for Wanhao Duplicator i3

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
