Sony - a6000 Mirrorless - Lens Cap Holder

I made this to hold my caps and for multiple sizes lens i have and the stock ~10mm strap.

I've made the mating surface to the cap slightly angled for better grip.
Also added a stop on each side to avoid the cap to fall if twisted, it's not 100% fullproof but good for most cases.
