I remixed the original with a slight adjustment to the length and width to fit some clip on sun glasses similar to the original designer's, but to fit on my Honda S2000. I bought the clip-ons a couple years ago from Walmart; Solar Shield 56 REC G. These had a slightly different profile and needed a little more tension for the spring to keep them on the model.
Printed in ABS on an Ender 3 Pro. Snug on the visor, but not tight enough to make a deep indentation on the visor. After a year of use it has gotten just loose enough to notice, but still stays in place without any concerns.
Print vertical with supports. I suggest using a brim.
