This is a slightly updated version the O.ZONE Mk8 from a gentleman by the name of Jung Rouk OH.

Things I've updated:

• Deeper recess on the lens tube and thicker lip
• Removed 3-axis rounded corners on the front side
• Changed the design of the grip to be beefier to compensate for the front weight of the lens

The original design can be found here: https://makerworld.com/en/models/1938699-o-zone-mk-8-modular-6x9-medium-format-film-camera?
