Pinhole cap with interchangeable pinhole inserts for Pentax 67 / 6x7 medium format cameras.
Recommended pinhole size for Pentax 67 / 6x7 bodies is 0.35mm for standard body cap and 0.40mm for shift / rotator pinhole cap.
Shifting / rotating cap can be shifted from center of the body cap all the way up to 28mm and rotated 360 degrees.
Design allows to take images with shifted pinhole insert or multiple exposures with pinhole insert shifted in different positions.
All of the caps will come with focusing insert. Viewing insert comes with 3d printed hole and will enable precise framing.
It's not intended for imaging. With any of taking pinhole sizes it's impossible to see image in viewfinder since it's too dark. With large hole in place of taking pinhole, it's possible to see low resolution image for framing.

Set #1 - Pinhole cap, 0.40mm pinhole insert
Set #2 - Pinhole cap, 0.25mm, 0,40mm and 0.50mm pinhole inserts

Pinhole was made from brass shim stock 0.001" or 0.0254mm thick.
Since this shim stock is extremely thin, it's possible to have some wrinkles/curvature due to temperature variations.
It's normal and it doesn't affect image quality.
Pinhole cap and inserts are 3D printed from ABS for durability.
Inserts thread size is M22.
Focal length can be varied with extension tube or macro bellows. There are several online calculators and phone apps
