yet another Towel Clip

<note: there is a new version (with a clamp spring)>

This is inspired by SilentSimons Tovel Clip but this was too big and can not hold anything in my household so I made it myself.

I recommend printing in PETG because the "the clinging effect" is pretty strong and PLA would maybe burst.

The two little holes are for flexible filament. To attach it, you need to heat at the ends to make it thicker. I tried a bit and found that fire is not a solution (it's too hot in several reasons) and holding the end in a metal pliers keeps the rest of the wire and the object cool.
I made a Video to show what I mean.

I designed the profile in Inkscape and made the 3D object in Openscad. All sources are uploaded.
