I made a square, rounded towel holder with screw covers.
printed in Polylite ABS but PLA or PETG should still work.
I recommend using the 3MF file as I used Variable layer height to improve the rounded parts, and added a modifier that makes the screw holes print at 100% infill to prevent cracking as its screwed into the wall.
I also recommend coating the outside with a waterproof coating such as polyurethane.
The author remixed this model.
