Test Information

I tested this hook using PLA+ at a 15% infill. I used a 20mm wood screw. 30lbs of resistance before breaking. Theoretically, using 4 or 6 supports (recommended) you could get up to 180lbs of bearing weight. Print at a 50% infill for strength. No supports are needed when rotated to be flat.

Dimensions:

  • Length: 45mm
  • Height: 45mm
  • Width: 25mm

V2 Dimensions:

  • Length: 50mm
  • Height: 50mm
  • Width: 25mm
  • Thickness: 5mm
  • Screw head diameter: 7.5mm
  • Screw taper: 23 deg.
  • Rounded edges: 2.5mm

Enjoy!
