ROG Ally battery holder

Quick battery mount for my ally. Internal dims of battery box are 139.5mm wide by 26.8mm deep. Slot is 50mm tall by 12mm wide if you want to make another battery holder that fits your specific battery. Included two clips for the ally, 8mm mounts battery lower on the device, 25mm a little higher up (personal preference thing). Your choice of vertical or horizontal mount. Vertical will flip battery orientation to stick up over the top of the device a bit but leaves a lot more room for your fingers on back. Horizontal the battery is like in the pictures. Does not block any vents in the back, sits away from backplate enough. Battery pack I used is UGREEN 20000mah on amazon. Need to print one battery grip, one battery box. Thick side of grip goes on bottom. No glue required, mating slots hold it in place. Slide grip the battery box, align the notches and clip over ally. Friction fit.
