This is a remix of Pyrex Quest 3 Strap Anker 533 Battery Pack Mount and SneckoSnek Oculus Quest 2 Elite Strap w/ Battery Mount.

This is a holder for the Anker A1263 (10,000mah) battery pack that fits the Quest 3 factory head strap. I use a single velcro strap to make sure it doesn't fall out. All buttons, ports, and LED's are accessible.

I'm including the 3mf file with the supports I used that worked really well for me. I'm also including the stl file.
