Reprapdiscount low profile knob

I created this low profile knob for the Reprapdiscount smart controller because the other knobs on Thingiverse were too tall for the installation and the rotary switch hole was not precise enough to prevent the knobs from falling off.

This knob is very basic in design. Feel free to adjust the SCAD file (included) to make the knob the perfect height that you require.

The low profile knob really helps to make traversing the menu of the smart controller more accurate.
