Parametric Hypercube Evolution Levelling Knob

thingiverse

I needed larger knobs for bed levelling and devised a plan to make them happen. After searching for something ready-to-print, I found an ideal design that matched my requirements exactly - it was created by Feeop042 on Thingiverse (https://www.thingiverse.com/thing:2896864). However, upon closer inspection, two issues arose. The shaft diameter of the original design exceeded my setup's capacity, and the 3mm screws I had were not countersunk as needed. To rectify this, I purchased 2 inch 6-32 screws and designed a custom clone of the original part. I have provided both OpenSCAD and STL files for your convenience. The design works flawlessly on my Hypercube Evolution printer, but it should be adaptable to other printers with some experimentation - simply adjust the variables until you find a configuration that suits your needs.
