Sectional Filter Ring

INTRO
I recently printed a Bhatinov mask for my newly acquired 10" Dobsonian telescope and needed a way to easily and securely attach it. Printing a mounting ring in it's entirety was out of the question since the bed of my printer wasn't big enough. So, I decided to print sections of the ring and glue them together. Knowing I would probably need rings for different filters (I also bought a premounted solar filter), I wrote a script for openSCAD so I could easily control different variables.

PREP
1) Download and install openSCAD
2) Download and save all of the files
3) Open openSCAD and then load the FilterRingSectonRevx.scad script
4) Get a ruler with a metric scale and/or some calipers

*OD (Telescope Outside Diameter) - carefully measure this and add 1mm*

*FilterOD (Filter
