These are the various pieces I used to assemble a utility belt inspired by the 1992 X-Men cyclops.

All pieces were attached using 2" polypropylene webbing in straps. I spray painted them to match and also spray painted the webbing, though if I did it all over again I'd skip spray painting the webbing.

The speaker boxes are designed to fit X Mini 2 speakers inside so you can wire up an iPhone to play music. But you could ostensibly just print more spacers and skip the speakers.
