Belt-Clips (or Holster) Recommendation for ThinkNode M1 & M5?

Wondering if anyone has a recommendation for a belt-clip for an M1 or M5?
All of my other (non-meshtastic) radios have a belt-clip I can use to clip to a belt, to a molle point on a backpack, or to a vertical bar on a shelf that holds my radios when charging.
