Wanhao i3 Thumbwheel alternative

myminifactory

This is another version of the thumbwheel designed to replace the M3 wingnut on the Wanhao Duplicator i3 / Cocoon Create / Monoprice Maker Select. Installation requires 4 x M3 nuts, which are pressed into place using long nose pliers due to the tight nut recesses. For added stability, consider using a locknut underneath the heated aluminum to prevent the M3 bolt from spinning. The larger wings on this thumbwheel make it easier to turn finely compared to round style knurled thumbwheels. Edit: After receiving feedback, I added a smaller version that should clear printer frames in cases where the original size was obstructed. However, I encountered no issues with the original size.

Edit: In response to requests, I incorporated 5.25mm and 5.75mm hex holes to accommodate different M3 nuts and various printer specifications.
