Bed Leveling M3 Nut Holder for Mix G1 Printer

After printing multiple times I would see the quality of the prints go downhill. I soon realized that the bed was becoming more unlevel with every print. This was because the nuts were spinning themselves off as the printer vibrated while printing. This holder stops that by holding the nut in place and not letting it rotate.
This is also a time saver when it comes to fine tuning the levelness of your bed because you no longer have to use a pair of pliers to hold the nut while turning the screw.

This part was designed in SolidWorks 2012 for the Mix G1 Printer M3 nut
