35mm Film Adapter for Medium Format Camera

I’ve made experiments with Leica film and a Mamiya645 a few years ago but loading the film was pain in the ass. I had to roll the 35mm film into the backing paper of the 120 film in total darkness. It’s much easier with this smart tool, I’ve got from a friend of mine. (He plans and builds cameras by printing them with 3D printer and there is always left-over material… Thanks Bálint!)
