Instax Adapter for Vintage Kodak Instant Cameras

This is an adapter for using Instax Square film directly in old Kodak Handle-type cameras. It consists of two parts, the main section, and a spring adapter plate.

I used PLA+, but any material should work, just make sure to use black so that there's not light bouncing around inside the camera.

For the main spring in the adapter, I used a .6 x 7 x 20mm 10 lap spring that was then stretched to be about 35 or 40mm. For the spring back plate adapter, I used a .6 x 7 x 10mm 6 lap spring that I cut in half and used both halves in the adapter.

NOTE: I've also included the picker arm adapter for Kodak EK4 type cameras, but it is still a work-in-progress and may jam or have other reliability issues, or worse, may cause damage to your camera.

NOTE 2: I've added the roller adjustment bracket for EK4 type cameras. They should be printed solid. You must disassemble the roller section to install these. Here's a video that shows how to do that: https://youtu.be/GLFBVRYM49I
