It's named PK-6142016, aka the 'Cycloptic Mustard Monster,' and is a 3D printed medium format camera with a Kreuznach 90mm f/8 Super Angulon lens attached.

Photographer Paul Kohlhausen has created what he calls a 'really precisely engineered box,' the PK-6142016 'Cycloptic Mustard Monster' medium format analog camera. Kohlhaussen designed the camera himself using Autodesk Fusion 360 and produced it via a 3D printer and SLS polyamide material. The Cycloptic Mustard Monster utilizes 120mm film and produces 6x14 cm negatives.

Kohlhausen detailed the camera on his website, where he explains that he used a Schneider Kreuznach 90mm f/8 Super Angulon lens designed for 4x5 cameras, with focusing being possible via fixed spacer brackets. Camera features include a viewfinder and a removable top plate for inserting film. In an interview with The Phoblographer, Kohlhaussen stated that he is considering launching the product on Kickstarter, but difficulties sourcing the aforementioned lens may be a hindrance.
