Rugged box for DJI Osmo Action 4 Camera

Rugged box for DJI Osmo Action 4 Camera

This has more storage space, SD card / ND Filter Inserts than original. 

6 x 30mm M3 bolts required - you can find these on Amazon & AliExpress.

Note: You can use full or half threads, I think half look nicer. 

The ND filter insert can be printed in TPU for best results.
