The goal of this part is to have 1 standardized mounting system for all lights, bike computers, cams and even your smartphone. The gopro system is very simple and strong. For this reason there are already a ton of connectors available for is. I tried my best to include as many as possible in this summary.

The bracket

This part is based on a part of the brand Moon. You can use this part on a self printed bracked or with the original Moon RB-15 and RB-35 brackets.

Connectors

Here is a list of connectors I could find on Thingiverse. I did not test them (all) so let me know if there are bad ones in the list.
If you know other compatible connectors, let me know and I will add them to the list. If one of the connectors fits other lights, cams, ... also let me know so I can update the name.

I also made a system to mount things underneath the saddle using the Gopro system. This already has a much wider range of compatible connectors, so check it out!

If you are interested to go even further standardizing your connectors in house, in your 3d-printer, in your car, ... you should checkout the modular mount system with a lot of remixes.
