Made a box that fits my Quest 3 for when I'm traveling. I printed it with a Bambu Labs P1P. The lid fit perfectly snug on both the PLA test print and the PETG one I am using. The lid is so snug that I can pick it up with a headset inside and not worry at all about the lid coming off.

It's pretty big to fit into a suitcase, but I have a decent size checked bag, and I didn't have the time or patience to make a custom contoured box to save every square inch. I might make one in the future if someone doesn't beat me to it.

I designed it to fit the Quest 3 with an elite style strap. It's a little roomier than the quest 3, in case I wanted to install some thin foam for padding. It just so happens to also fit a Quest 3 with the new BoboVR S3 Headset if you crank the strap most of the way down.

I used PETG for the case I will travel with. I did 100% infill for the bottom. It's plenty strong but quite heavy. For the lid I went with 2 wall loops 40% infill, cubic pattern. It's still very strong and quite a bit lighter.

To give you another example of print settings and strength, I first printed one out of PLA to test the fit. At 1 wall loop and 10% infil, it was strong enough to support me (170lbs) when pressing down on the lid with my hands and lifting my feet off the ground. The middle was much weaker when laid on it's side, but stil impressive for such thin walls and very little infil. I absolutely recommend at least 2 wall loops, and minimum infill at probably 20% if weight is a concern. PETG will be better for impact and heat resistance over PLA.

Do whatever you want with these files. I just measured the headset and messed around in Plasticity until I had something that I figured would probably work.
