Xyz Da Vinci Heat Bed Thumb Wheel m3 Square nut

This was made for Da Vinci 3D printers but will work for all 3D printer beds and things, I used a square nut to give better grip and prevent nut slippage :) as always .sldprt included. all be it a crude quick design....

If you remix this or make alterations, please upload them back with all original solid works files so that everyone can use them, and people that don't have solid works can then benefit from the modifications,
Thanx

I Always add the original creation file not just the stl,
