3d Printed Gopro Battery Grip

I really like my Gopro Hero 10 action camera. But when you are vlogging, the battery is draining pretty fast. Therefore, I decided to create a battery grip for extended recording time.

The housing is a simple design using Sketchup. It consists of several 3d printed parts which are easy to print even on budget 3d printers. Most parts are designed to press fit in order to avoid the use of glue and to be easily changeable. I recommend using ABS(+) but PLA and PETG will work too.

The electronics consist of a charging, a step up and a USB module. I decided for this modular approach to keep the overall package rather small. However, this means that you need to solder.

The electronics are powered by a single Li-Ion cell. I went for a single cell to keep the weight and size of the grip down. I recommend using a 21700 battery (up to 5000mAh) for longer run time, although a more common 18650 (up to 3500mAh) will also do the job. Overall, this should help to extend your action cam's battery life 3-5 times.

You need:
-I recommend ESUN ABS+
-Li-Ion cell e.g. 21700
-USB module
-DC step up module
-TP4056 micro micro USB or USB-C
-wire
-M5 nut
-2x M3 nuts
-2x M3 12mm screws

I hope you enjoy my design. Have fun and stay safe!
