Mamiya 645 Crank

Mamiya 645 Crank – Replacement / Upgrade

Whether your original crank is missing or you simply want a more slim version for your Mamiya 645, this is a fully modeled replacement part.
I printed mine in carbon-fiber PETG, which provides excellent rigidity and durability.

The crank is split into several components to ensure optimal print quality and to allow all necessary degrees of freedom during rotation.
The assembly is intentionally tight, so don’t worry if you need to apply a bit of torque when mounting it onto the camera.
