Sony A7s to 2" Telescope focuser adapter

thingiverse

This is an adapter to connect a Sony camera to a standard telescope focuser, I've tested this with ABS and it works fine but it's a bit tricky to print because of the tight tolerances so you'll probably have to edit the model. The tabs that lock the adapter to the camera aren't as strong as a metal part so take care and use the camera strap to prevent a fall.
