Sometimes you need a knob that is just big enough to comfortably turn a screw by hand, without applying much force. These mini knobs are designed exactly for that purpose. They fit individual nuts or bolts of the selected size.
Printing recommendations:
Material: PETG or PLA
Layer height: 0.2 mm 3 perimeters, 5 top & bottom layers
Infill: 15% is sufficient
For multiple parts: use sequential printing (one after another) – faster, cleaner, less stringing
Print with the hex opening facing upward
09.11.25 Update: Some files did not have the correct hole diameters. I uploaded corrected files today.
22.12.25 Updae: added M3 Knob. It is very thight, as I did not want the nut or bolt to fall out. Rather pull it in with a bolt or nut to have it snug.
