Ultimaker Control / Knob

Ultimaker's idea of an ergonomic control knob is pretty poor, while loosely aesthetically pleasing, to use, its actually a really poor design as its hard to be precise with it. I redesigned the control to stick out, and be far easier to grasp and manipulate!

Fits my UM2, should fit any other Ultimaker 2, 2+ or 3 :)
