Summary

This is a pair of lens hoods for the Sputnik Stereo Camera. The functional aperture is 33.3 mm with 4.7mm diameter corners located approximately 41 mm from the entrance pupil. It is designed primarily for use at f/22, f/16, although the vignetting caused at wider apertures is not much more than the inherent vignetting of the Sputnik's unhooded lenses.

The Fusion 360 file is provided in case you want to make changes. Perhaps one change that may be needed is the lens separation. The parameter named "rim-to-rim" controls this and refers to an outer dimension measured across the "hubs" where the hood press-fits onto. Refer to the image where this dimension is indicated in red. I have personally tested the lens hood on Sputniks with rim-to-rim spacings between 89.9 mm and 90.9 mm which all fit properly with the design dimension set to 90.5 mm, but perhaps it will not fit properly on all Sputniks outside this range.
