Summary Works pretty well although the light doesn't travel far up the plastic like the original clear one. If the room is dark enough still looks good. I printed it with glow in the dark filament to help. They turn out strong, but my child still breaks them regularly at school. I think I'm on my 7th print which helped in a way to refine the model a bit. Print Settings Printer: Monoprice Maker Select v2.1 Rafts: No Supports: Yes Resolution: .1 Infill: whatever Notes: Definitely need supports and good bed adhesion. I've done several different infills from solid to none and they all seemed to work about the same.
