I realize there are much cheaper alternatives, but I was wondering what the ballpark would be to 3d print a classic Astroscan dew shield. I'm guessing there's no existing model for it, so it would involve CAD work. Maybe a junior college 3d modeling project?
3d print Astroscan dew shield?

Interesting thought. Once designed, it would be an easy print to do with no supports or anything special.

Edmund was still selling dew shields a few years ago.
They must have been old stock, because I bought one, and the first time I installed it it cracked immediately. I eventually rebonded it but I'm now more careful if I consider putting it on.
I would assume you should be able to either buy one or locate photographs of them. There is a cutout, as I recall it, for the focuser.
I haven't started my 3D printing entry yet, but I would imagine it is not a difficult piece to make or lay out in CAD.
Edit: I located great photos of the dew shield in this thread
Edit2: that thread talked about finders, and I have one of the original sheet metal ones but always wanted to attach a prism, cheap diagonal body, or small RA mirror to it to avoid the bending over nonsense.
