Parametric Hypercube Evolution Levelling Knob

I wanted to make some larger knobs for bed levelling, and figured out a good way to do it. So I started looking for something ready-to-print, and found one that looked like exxactly what I needed. It was made by Feeop042, (https://www.thingiverse.com/thing:2896864).

Turns out it was close, but there were two problems.

The shaft diameter was too big for my setup, and the 3mm screws I had were not the countersunk ones. So I bought some 2 inch 6-32, screws, and designed a clone of it

I have provided OpenSCAD and STL files. It works fine on a Hypercube Evolution, but should work on other printers. Just play with the variables until you get one that works for you.
