In my small workshop, I drop a ceiling-mounted dust hose when sanding. It doesn't twist well, so I had to fight it. This fixes that. I cut the hose and inserted my rotating pivot—one in the middle, another at the end for extra flexibility.
- Print-in-place (needs light support outside).
- Fully parametric (Fusion 360 file included).
- 27 pre-made size variations for different hose couplings.
- Tested on 38mm to 38mm—post your results if you try other sizes!
Printing & Assembly
Print as oriented in the file. The "inner" side should be on the build plate. A small support is needed for the upper lip—I used tree supports.
Designed with 0.3mm clearance for free rotation without air leaks. Printed at 0.2mm layer height, 4 walls, PLA (PETG recommended for heavy use).
Modifications
Adjust tolerance in Fusion 360 if needed. If resizing one side much larger, pick “Side A” (lower part) and increase spacing to keep angles under 45° for printability. Resetting to the original and redoing changes works better than iterating.
