I made a set of telescope rings and a long dovetail for my 102mm refractor, I didn't want to spend $100 for a set of metal rings that “might” fit. So I designed my own!

I printed the rings and dovetail in ASA from Overture, I wouldn't recommend PLA due to the dew/moisture that is ever present during stargazing and may structurally fail at one point.  

For the rings I also used Archimedean Chords for the bottom and top fill patterns as well as gyroid infill for the flexibility advantages, I don't know if this actually helps but so far it works great.

I added the .step files in case you want to change things, let me know if there are any issues!

Hardware used:

Rings-

8x - ¼-20 x 1" socket head screw cap bolts

8x - ¼-20 nylock nuts

Dovetail

4x - 5/16-18 x 1" socket head screw cap bolts

4x - 5/15-18 nylock nuts 

Thanks and Clear Skies!
