After repeatedly bumping into drawer knobs at tight quarters, I put these together. No more bruises.
The dimensions were chosen based primarily on specific functional considerations (read: minimize bruises). However, the design is parametric (diameter, height, notch size, screw depth), if you find the notch too small (or your fingers too large?), the proportions too ugly, or whatever. Caveat: the Minkowski sum to get rounded edges takes about an hour to render (Core i5, 16G RAM), hence not releasing for Customizer. :)
