I got tired of losing my AirPods Pro holder or not being able to get them out of my pocket when sitting in the car. I decided to make a holder so I could either attach to a belt or my waistband or to a watchband. This turned out pretty good. It has a stop so it won't drop through while allowing the cover to open without removing the case from the holder. It has an open bottom so one can still charge the case using the lightning connector but also (if you orient the AirPods case in the holder correctly also charges wirelessly without removing from the holder.

The "clip" is a little serpentine so the holder doesn't come off too easily.

I have done something similar for the AirPods: https://www.thingiverse.com/thing:4803014

It prints pretty well without support if oriented correctly.
