Meta Quest 3 head strap battery pack mount
A counterweight cradle that straps a slim USB power bank to the rear of a Meta Quest 3 or Quest 3S standard head strap, extending play time and balancing the 515 g headset. The pocket is sized for a 100 x 52 x 26 mm bank such as the Anker 10000 mAh or a slim 5000 mAh cell, with 0.5 mm clearance, an open bottom for the USB-C lead, and two 25 mm wide slots that the rear strap threads through. A curved 3 mm back plate spreads the load across the strap pad and a 15 mm elastic loop keeps the bank from bouncing during Beat Saber. Print it on its flat back with 2 mm walls.
Battery straps for the Quest are pricey and lock you into one battery. In SpeakCAD you type your power bank's dimensions and strap width, preview the cradle in the browser without spending anything, adjust the curve in the chat and download the STL.
