PickleClip

We found a pickleball at work and my coworker wanted to carry it around easier. He clipped it on a belt loop with a glove clip, use what you want.

2 parts are held together with a bit of filament as a pin. No glue needed.

Depending on your printer tolerance there's a second model with a 2.2mm hole for the pin. The initial one we printed out was too tight at 2.0mm but I just drilled it out 

Used the geometry of the clamp, ditched the coupler
