Replacement Film Advance Knob for the Bronica SQ-Ai


SKU: N/A Category:


This is a replacement knob for the Bronica SQ-Ai. It is 3D printed using Atomic Filament ABS and my Voron printers.
When I purchased my Ai, it didn’t come with a normal knob or crank and they seem to be hard to come by. As a result, I designed a 3D printed knob which friction fits onto the lugs. It has been working very well for me so thought I would offer it up for other folks that are in the same boat.
This works for the Ai ONLY. It does not work on the pre-Ai models as they use a different mechanism.
This is ONLY the knob. The camera is not included. It is just to show what the knob looks like attached to the camera.
