Experimenting with sphere retention structures which can be more reliably manufactured using FDM/SLA processes.
It's "The Octagons" this time!

Updated the Git to reflect this latest attempt.

Oakee doakee... Got the prints back. Sphere retention is a bit too tight with these dimensions. It takes significant force to engage sphere. Will adjust octagon dimensions for greater accommodation.

Note: Material is black photopolymer resin. SLA process. No sanding.

(Can you tell I'm nervous about videoing this?)

Having gone through the batch, it seems that, (as the Smiths never sang): "Some Prints are Tighter than Others"

I will leave the model as it is and folks can make their own accommodation one way or another.

To prove to myself that the optics calculations are valid, here are two optical housings with yellow velum representing the sensor surface. Right is the original circular aperture with no sphere installed, left is the aperture including interfacing sphere. Light level at sensor surface is at least 50% greater with spheres installed.
