Description

Update 3/31/23: Added version for Polaroid 600SE lenses.

----------

Update 1/18/2022: Made some improvements to the lens locking method for a much more secure shooting experience. The screw is now no longer a set screw, just a lock screw so does not need to be tight. Flange distance was also refined a bit. Changed the bottom to make printability better without supports in that area as the angle was hard to print sometimes.

----------

Make an MP Wide 300 camera mod with this lens adapter. Use any Mamiya Press lens on the Fujifilm Instax Wide 300 camera.

Included are files for the cold shoe riser block, as well as cold shoe bracket for Luxjet LS-1, or IIDA DM-01 and similar laser distance measurement tools. The cold shoe feet on the bracket is oversize in height so you can sand down the bottom to match your cold shoes.

Calibrating with ground glass will be difficult because instax film does not always push as much forward as the ground glass will (due to the chemical pods). Also the film is wavy throughout the surface and can vary 0.65 - 1mm from center to edges.

Just make sure that it is 15.30-15.35 and no less, but no greater than 15.5mm from where the lens seats on the adapter, to the bottom of the adapter. This should get you sharpness at both infinity and 3.5ft. You will want to control this with first layer height depending on your material and printer or maybe slightly scale the model up/down on Z-axis. If you're over then you can sand the bottom just make sure to push it down all the way when you glue the adapter on. 

I experienced -0.25mm from Ender to Prusa so be aware of that. The sharpness difference between the printers wasn't much and barely noticeable unless you have the frames side by side.
