I needed a headphone stand, and wanted it to have a place to stash the cord (to keep the Roomba from trying to eat it).
There are a lot of ugly gotchas in this print, but it worked okay for me. In particular, the rounded sides are absolute messes, but I can't find a way to get them smoother in FreeCAD (and trying to fillet them crashes it for me).
This is actually a curved part (doesn't look like it, but it is), so you'll probably want to manually lie it on one side before trying to print.
The author marked this model as their own original creation.
