Graflex Speed Graphic 4x5 Magnifying Finder

First, credit where it's due, this was modeled by me to work with the Graflex, but was inspired by this model designed for the Intrepid 4x5 camera https://www.thingiverse.com/thing:5565756 

This is a magnifying finder hood for the Speed Graphic 4x5 camera, which mounts into the spring-loaded clips used to hold the metal pop up hood found on the ground glass. There are a handful of non-3D printed parts required:

• Four M3x16 bolds with nuts
• A 50mm diameter, 150mm focal length magnifying lens - I used this one available on Amazon: https://www.amazon.com/dp/B0791MS5GJ?ref=ppx_yo2ov_dt_b_fed_asin_title 

Assembly is simple - sandwich the lens between the two holder pieces, align with the finder hood, secure with the four nuts and bolts. 

Should give a nice clear view of the ground glass, with about 90% coverage - you might have to remove the hood to check the corners if you're trying to be super accurate with framing.
