This is an alternate door for the GoPro Hero 8 which allow connecting the USB-C charging cable for operating the camera with an external power source. Typically long timelapses or long drives, etc.
It is similar to the ULANZI G8-7 GoPro 8 Chargeable Battery Lid (https://www.ulanzi.com/products/ulanzi-g8-7-gopro-8-chargeable-battery-lid) but 3D printed. I would have bought the Ulanzi onz but no-one seem to have it in stock close to where I live and I needed a solution to make timelapses.
It is of course not water proof at all but it is already much better than no door at all :-)
Printed in PLA. No supports.
