Link to battery holder V2 with a more secure design and less "moment" weight so it feels lighter than V1: https://thangs.com/mythangs/file/488533

this is a remix and my first design so that you can have a power bank plugged into the oculus while playing, since my power bank has a built-in USB-C cable

The dimensions of the hole for the power bank are 140x21mm big with a little wiggle room for ease of use, if the 140mm direction needs to be bigger or smaller you can go into cura and make a support blocker over the hole, highlight the support blocker and go to "per model settings" and in the modify settings go to infill settings only and adjust the "horizontal expansion" setting.

there are clips on the 3d design to clip onto the vent gap, but if your clips don't print well like mine, use some double sided tape, rubber bands or string to keep it in place, where string would be the best choice for a permeant solution, and the tape and rubber bands for a temporary solution.

if you want the same power bank i have you can buy it from this amazon link: https://www.amazon.co.uk/gp/product/B097819MNF/ref=ox_sc_act_title_1?smid=A3H4EX84EP2E60&psc=1
