A storage box to protect a Hero 4 Session camera. The lid is a snap fit. I glued a piece of felt into the bottom and lid to protect the lens from scratches no matter which way you insert it and it also makes for a perfect fit. You can shake it and the camera does not move inside even though there is a tiny amount of space around the sides to allow easy insertion and removal.
I suggest .2mm layer height, solid infill. No need for support.
