Assembly video
Watch the full assembly walkthrough to see how all components fit together.
Printing
This variant uses the standard PitClamp Mini print settings with an additional wall on the Ring component.
Print settings
| Setting | Value |
|---|---|
| Walls | 6 (Ring: 7 walls) |
| Infill type | Cross Hatch or Gyroid |
| Infill percentage | 10% |
| Supports | Normal (Snug) with 3° threshold angle |
| Support placement | Allow supports on part |
| Seam | Nearest (or your preference) |
Recommended filament: PLA+ for optimal strength and durability.
All parts must print in the default file orientation. Printing Base components in other orientations causes structural weakness that may lead to failure under load.
Print-in-place option
If your printer is well calibrated and your material has optimal layer adhesion, you can use the print-in-place Upper+Handle variant. Find this in the /Non-Standard folder—it's included in the Generic 3MF file by default.
Critical area reinforcement
For maximum strength, use a cube modifier to force 100% infill at the critical stress area shown below.
Adding 100% infill at high-stress areas significantly increases the load capacity and longevity of your mount.
