Clamp to hold things like towels, clothes or fabric.
Prints lying on front side without supports or special settings. I printed it with .2mm layer height and 15% infill.
The magnet version can be loaded (press-fit) with 7 5x3mm round magnets. The non-magnet version can be attached with tape.
For the magnet version and depending on the surface I recommend to use some additional anti slip pads.
