The file 'Universal Mask Vent Clip 3D Printer Model' is (stl) file type, size is 47.2KB.
This is a clip you can attach to your car vent and hang your mask.
I remixed the vent connector from https://www.thingiverse.com/thing:526257 and simply added hooks directly to it.
I recommend tree supports connecting to the base only, for easy removal and clean printing.
I printed mine in black PLA, but I'd recommend PETG or something that can withstand temperatures better if you plan on leaving it out in the sun for a long time.
Update 3-9-2021: Added a version 2. This has a shorter, tighter connection with the vent blade and works better for my car's vents. The two arms are also a bit longer and stronger. Overall it feels a bit more sturdy, with the added bonus of printing faster. But print the original one if you need a longer connection for the vent.
