Guide scope finder rings

Holder rings for mini astro cameras.

Compression fit, fits standard finder shoe.
Can be used as guide scope, wide field cam etc....
Long version for QHY cameras (images QHY 715c)
Short version for Touptek Or ZWO (tested on Touptek 678c and ZWO 290mm mini)

Print on front, with one rind flat on the build plate, and supports supporting the second ring.
This was printed in PLA+, will need to be stiff for guiding, ABS or PETG are a bit too flexible or soft for that (haven't tried though...)
For wide field this can be printed in any filament, glow in the dark can be cool.
Supports are a Must! Use tree supports on build plate only.
I used both 0.4 and 0.6 nozzles, both work fine.
Infill shouldn't matter much, use 20-30% should be ok.
