A 3D-printable reference plate designed to visually compare common cinema camera sensor/film gate formats. The model uses a 15-perf 65mm film frame (commonly known as IMAX 15/70) as the outer boundary, with nested gates representing formats.

Formats:
Super 16, Super 35, Full Frame (36×24), Eterna 55, Alexa 65, and 15 PERF 65mm. (WRITTEN ON BACK)
 

Each frame is proportionally scaled to help illustrate differences in field of view, crop, and image area at a glance. It makes a useful tool for filmmakers, photographers, and anyone learning about camera formats.
 

The design is an accurate 1:1 65mm film strip and to-scale gate/sensor sizes.

You can use the perforation holes for keychains or anything you want!
