Celestron OAG 2" Mounted Filter Holder

Allows you to mount filters into the Celestron OAG's 12mm cavity. I'm surprised Celestron didn't include an M48 thread on the inside of the 12mm adapters in the original design.

The print is designed to fit very snug so it can be held by friction. Handles on the sides are for easy removal. I just leave each of my filters mounted directly on these holders.

It doesn't take much friction to screw in the filters snugly. Do not over-tighten the filter or the plastic threads will strip.

I used PLA at the highest quality settings due to the small threads.
