The included STL has a back curve on it to match an 8" (205mm) cassegrain telescope. I needed it to replace a broken rail that mounted the 1x red dot scope on my Celestron 8" telescope.

If your scope outer diameter is significantly different, you'll probably want to change the tubedia parameter.  Everything else is pretty easy to change as well.
