Dual Color M3 Thumbwheel Wanhao Duplicator i3

Dual Color Thumbwheel (or not). It was designed to print readable numbers, be printed in dual color, and have a grippy outside surface. It has markings for every .1mm move in Z and has an outside diameter of 23mm.

I printed this with my Wanhao Duplicator i3 and switched filament mid print to black.

You can just print in one color and color the numbers, but dual printing colors looks SO MUCH BETTER! And come on you've been wanting to learn how to do it anyways........

I like to use a M3 x 0.5 Stainless Steel Nylon Lock Nuts with these.
