Windchime Clamp for Flashing

My mother wanted her wind chimes hung up but my father didn't want to put any holes in the porch ceiling. Having a 3D printer, naturally I devised something to keep the peace. The first one I printed entirely out of PLA and it works fine but I made a few tweaks on the second iteration and printed the foot out of TPU. Both seem to work well but no idea how long they will hold up in the elements. Design is intended to have a ¼ - 20 eye bolt threaded into the plastic as the tensioning and hanging apparatus. I considered making one where you could embed a nut into the clamp body but fail to see the point. If anyone wants such a thing lmk and I'll get to it eventually.
