Custom parts and enclosures

Utility belt: Battery holder

Holds a cylindrical 5V USB phone charger, with a slot for a thin belt. I wear one on each hip.

Utility belt: Triangle pocket

Holds a small controller (or your Almond Joy), with a slot for a thin belt. I wear these on either side of the center buckle.

Utility belt: Center

Has a slot for a thin belt, and also a secret storage spot where you can stash stuff from the back. Great for earplugs or other stuff you don't want to lose.
