In one of my recent videos I share how I shot with the 4×5 instant back (Lomograflok ) from @Lomography. In that video I shot with my Chamonix 4×5 camera and I mentioned that we need to use a spacer every time we compose a shot.

Another point I mentioned is that if I were to mount this back on the camera I would need to remove the ground glass frame. The Chamonix ground glass frame is easy to put back ( one hand to slide the frame in)but difficult to remove ( you need 2 hands to lift out the 2 spring arms) and that is kind of troublesome if you have to do that for every shot.

So I decided to 3D printed a ground glass frame that already has the spacer built in and it’s also much easier to remove and put back.
