Concave Fidget Caps - No Supports

thingiverse

I discovered numerous concave fidget spinner caps online, but nearly all of them necessitated printing with support material except for Turrboenvy's remix of ftwelve's Textured Concaved Fidget Caps. I desired the caps to be larger than ftwelve's design. Eventually, I was able to grasp rcolyer's openscad screw library well enough to use it and create exactly what I wanted. This printed perfectly for me using 0.2mm layers with PETG. I did not attempt any other layer heights or materials.
