Hat/Headphone Hanger (customisable)

thingiverse

A versatile holder for rounded objects such as headphones and hats is designed with a parametric approach. To tailor the support's fit, customize the radius according to the item's shape; I discovered that a roll of tape worked effectively for both my hat and headphones, so I measured their diameters and halved them. The mounting plate scales in proportion to the radius, resulting in larger plates for greater radii. For secure attachment, I utilized 3M double-sided foam tape on surfaces. I've kept $fn visible for adjusting the curve resolution; a setting of 100 should suffice, but you can increase it for smoother curves.
