Rotating vacuum hose nozzle - print in place

thingiverse

This adapter fits standard ribbed vacuum hoses perfectly. I based its design on the one I accidentally broke, but it's now stronger than ever. The adapter has two main parts: the lower part that screws onto the hose's ribs and the upper part that connects to tool dust ports. These two parts rotate freely around each other so you can attach a tool without restricting the hose's movement. I printed mine with PETG material, 0.2mm layer height, and minimal supports in the slicer settings. I set an overhang threshold of 10 degrees, which allowed only the base of the outer shell and the start of the internal threading to receive support. The rest of the design prints without any support at all. It took around 5.5 hours to print on my Prusa MK3 machine.
