The long-awaited sequel (lol) to my first 3D printed mirrors video, where I take your advice and switch to UV-cure resin, get great results, but not good enough results, and then cheat by silvering a chunk of regular acrylic sheet! This video is a collab with (and the idea of a saddlepoint mirror was from) Steve Mould, so check out his video about this very saddlepoint mirror after you watch this!

A completely different method for obtaining 3D printed mirrors via electroplating that I didn't talk about here but is very cool:

The cool video I referenced about splines - relevant G2 continuity bit at 27:49 (but watch the whole thing!):
