3/15/19 UPDATE : Just notched out he left side ( Modified stl ) so you can plug the camera in and charge while its in the mount. Not as tight of a fit , but gives you that option to charge . I suggest using the original one without the knotch if you want it to hold better.
This fits the GoPro Hero 7 and should then fit the Hero 6 and Hero 5 as well.
I accidentally used a gopro screw thread on this . Still works , but you may have to tap out hole. I just took a 1/4 inch bolt and screwed it into the bottom threaded hole to make it bigger to fit the tripod . Not hard at all. Makes it stronger this way.
Also , I was going to put the Gopro name on the side of this , but figured you would need some supports to keep some of the lettering looking good. So instead I made a quick name plate that you can change filament at points in the print to give it a multi color look. I have acrylic glue that is awesome that I swear by , so I will just glue the name plate on the front of the mount. I did this plate with 100 infill , .2 layer height and switched out the filament on layer 13 .
