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
