This is a mount and retaining ring for an 8 inch diameter telescope mirror. I recommend printing this out of rigid material, like PETG+CF or PLA+CF, and make sure you measure and compensate for any material shrinkage, as the tolerances on this mount are tight.
The ID of the mirror pocket is 8.05 in The OD of the mirror pocket is 8.75 in Base to center of mirror is 5 in Footprint of base is 4 x 4 in
The holes for the retaining ring are sized for 6-32 threaded inserts. (McMaster PN:93365A132)
Mounting holes for the base are 0.27 in OD with a 0.5 in clearance around the head of the bolt, set 1 in x 1.5 in centers.
