Modern ish eyecup for Canon A-1?

Hey everyone, does anyone have a modern style eyecup on their canon A-1? My original eyecup finally broke in -20°c weather and frankly it was a bit of a pain in the ass, so i would like to replace it with something more modern!

I have seen a 3D printable one, but i dont have access to a 3D printer that can print PLA or other soft rubber like materials. Having one printed would be prohibitively expensive as well unfortunately.
