I liked how the original Meta Quest 3 box displays and holds the Touch Plus controllers, and having recently bought a Syntech case for my headset, I found it a little awkward to strap the controllers into the case. 

I found Aerandir14's model and figured I'd create a modification to open up this compartment to allow for more versatility.

Aerandir14's model would still be good for if you don't want your small items to be too insecure in your headset. Mine is if you're confident your items won't come loose and you want easier access to them.

I'm printing this upside-down in PETG. Thinking about it, there isn't anything really stopping you from printing this in PLA.
