Thank you Scott Walsh for permitting a remix of your great design. Here's his video which describes how they're used and some helpful tips on putting together dust collection system.

No support needed. PrusaSlicer complains about unsupported bridging, unfortunately this is required for the hinge printed in this orientation. I used .2mm layers, 20% gyroid infill and 3 layer walls.

Loosening the hinge from the initial print can be accomplished with some gentle taps. The key is to break the material between each layer without damaging the hinge. I added some internal walls to help prevent this.

Use #8 flat head screws to attach to wall/ceiling. Use a #6-32 1 1/2in machine screw for the clasp, with #6 washer and nut.

Differences of the remix compared to the original

  • Added 5in versions.
  • Added horizontal wall mount variations.
  • Brackets in vertical mounts print without support. (55-60deg angles, smooth transitions)
  • Increased size of M3 nut/bolt holes to accommodate #6/32 SAE
  • Increased layer separation for hinge.
  • Added 3 small inner tubes creating interior walls - adds to rigidity.
