Nice job, what CAD program you use to draw these if I may inquire? I've made a few thing now for my boat as well with my printer that I can no longer get..........
Also, looks like you used PLA filament? If so and the rings are even outside? Then no worries on the UV, PLA is UV safe!!......I have a PLA piece I printed up and threw up on my roof 3 years back. For 24/7/365*3, it has been exposed to not only +120'ish degrees F full sun sitting on composite shacks each summer but, it see's every things else that the NW weather can throw at it.
