Wanhao i3 Thumbwheel alternative

This is another version of the thumbwheel to replace the m3 wingnut on the Wanhao Duplicator i3 / Cocoon Create / Monoprice Maker Select.

It requires 4x m3 nuts to install. The nut recesses are quite tight, i recommend using long nose pliers to press them into place.

I also reccommend using this in conjunction with a locknut underneath the heated aluminium to stop the m3 bolt from spinning.

I prefer the larger wings, they are easier to turn finely than the more popular round style knurl
