Inner and outer knobs for TC Electronic G-Major 1 and Triple-C devices. Possibly to fit other devices from TC. Inner knob has clearance versions. Every 3D printer has different possibility about precision, so I created clearance files which increase space for shaft. So just print model with zero clearance and check it. If so tight print again and choose higher clearance files.

Print instructions

• PLA
• 0.1mm layer height
• Infill 100% (Outer knob), Infill 20% (Inner knob)
• Look to 3MF file for detailed print settings in PrusaSlicer.
