This mount is a mashup from Paul park's and rimzler's design ( https://www.thingiverse.com/thing:4035039/files and https://www.thingiverse.com/thing:4118143 )
The case itself is inspired by Rimzler's design, which i liked better over Paul Park's design. But the lack of adjust-ability did not work for me. This design is a mix of best of both ( in my opinion ;) )
AUW is around 147 grams at the moment
Also added a SD card slot so the GP does not need to be taken out of it's case.
