This is a battery holder for the DJI Goggles2 battery. It has a clip that fits over the part of the strap that returns (the double strap thickness).
Works really well. Just shorten the length of the battery cable. The battery is not that heavy and fits nicely on the strap of the goggles.
Print with full support with around 40 % infill. See picture.
Carefully clean the supports afterward (particularly the inside). If clean, the clip should securely hold the battery.
