The Open 6x12 is an open-source 6x12 medium format camera. This camera takes 4 frames per roll of 120.

I currently have Lens cones for the Graflex Optar 135mm f4.7 and the Schnider Super Angulon 90mm f8 made and ready to go. Price includes the body and hardware, completely assembled. Interior of body and lens cone will be painted matte black and felt flocking is also used on the interior. These lens cones are hyperfocal at F/22.

Please reach out to me if you have a different lens other than what is listed, I would be happy to make lens cones to suit your lens!

I can also make lens cones that accept an M65 helicoid adapter.

Example photos added, taken in may or so with the Graflex Optar 135 f4.7 @ f22 on Kentmere 400.
