I've made a small change in the design so the camera gets tighter when attached to the GoPro connector.
I left the old one in case you need a looser case
VERSION 2 !!
Case for GoPro Hero 3+ with holes for microphones and all buttons.
Bridges optimized for FDM 3D printing
I created this case to be used with GoPro Hero 3 and 3+, so you can attach it to a tripod and still have all the inputs and mics available.
The bridges are chamfered so few support is needed to be printed out using FDM 3D printers.
This is version 2, with bridges corrected and wall thickness a little small.
