Years ago I broke the cover for my basement mancave ceiling light. Didn't want to spend 60+ bucks on a new glass one so this is my first model and practice fixing things around the house to prove to my wife this thing isn't just a big toy.

I printed it in transparent PETG vertically. With the infill and little bubbles that are common it diffuses the light nicely but allows more light in than the frosted one that it replaced.
