Cold Shoe on GoPro style curved helmet mount

This should allow a low profile mounting of a lav mic such as the Rode Wireless Go/Me/2/Pro/3 onto a helmet. Simply print and add your own 3M double-sided tape on the underside.

Recommended you print with ASA or ABS… PETG would probably do however depending on the direction of impact the cold shoe may not be super structurally resillient. Potentially worth printing on an angle to change the orientation of the layer lines to help with that. Minimum 25% infill. 

Please note: This is an untested design. If you're willing to take the gamble, please let me know how good or bad the tolerances are after printing - I'm more than happy to revise and re-upload if it's not quite right.
