Bronica ETRSi Film Advance Big Knob
thingiverse
I designed a film advance knob for my Bronica ETRSi, but i guess it will fit all ETR models. My camera didn't came with a crank, so i used it without a crank for nearly 10 years and it's time for an upgrade. The design is pretty straight forward and needs no support. I used a brim, but you don't have to if you trust you adhesion method.
