This is to make a more robust Corsi-Rosenthal filter-box, using the CR30 printmill to make 522mm long mounts for the filters. It can be easily printed on a smaller printer by cutting the beams in half, or even thirds - threading them onto the 2020 rod makes this build fully modular.

I wanted to use my modified CR30 for something useful - and this was the first project that came up. My hometown's been hit by the Canadian wildfires pretty hard lately, and our makerspace, too, could use more filtration.
