Designed to fit on the handlebars of my fourwheeler (quad bike, for those inclined); will hold many things, but was originally made to hold a JBL Charge 5.

Fits handlebars ~19.5mm

Print 2 of each.

Print straps in TPU - replace with rubber bands to hold other things, or try scaling.

Print mounts in ABS for best results - PLA works, but tends to warp over time.

Requires some nuts and bolts or some other form of hardware to hold everything together.
