I like the affordable UVEX sunglasses. I’m not sure which model they are. Apparently, there are many very similar models. Since the coating on the temples always wears off for me, I made some replacement temples with FreeCAD. The model is just one temple—if you need the second one, it must be printed in mirror image. The 3MF file already includes a mirrored version. I printed them without supports using PETG.
