Print and clip on! It's sized to grip the hex dial firmly but not so hard that it's difficult to get on. At least, on my printer. Your mileage may vary.
Filament: PLA
Layer height: I used 0.20mm , same as the clamp itself. It's probably worth matching the two.
Perimeters: 3
Infill: triangle, 15% but probably doesn't matter too much.
