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 of bellows. There are several online calculators and phone apps
that can be used to calculate optimal pinhole size for specific focal length and coresponding F stops.
