Hi,
Fully printed and functional telescope printed in PLA(except for the aluminum poles and the optics of course)

Very nice! Is there a sock that fits over the tube to prevent people from putting their hands on the mirror? Are the fan there to prevent condensation from forming on the mirror?

Nope, there's no protection against 'greasy' hands..;-) There's no need because, except during open door, there's only me and occasional friends observing through that scope. So no worries about the optics..
The 3 green fans are there to cool the(selfmade) primary mirror as fast as possible. The 2 other fans serve as 'boundary layer' remover. These two will also help cool that primary mirror before an observing session starts. I will also use these two upper fans occasionally to remove condensation.

Can you use the scope while the fans are running, or do you have to turn them off?

Wow, that's seriously impressive.
Thanks..!
But what you don't see is all the work of our electronics guru(Guy), The man on the right side in the picture.
When I drew this project I did not want to see any wiring around the scope. So I drew most of the printed parts with 'canals' in them. iow all electric wiring is tucked away, a nightmare to draw but most of all to assemble.

Chris,
That's very impressive, and a great example of a very practical use for a 3D printer.
Anything you can imagine you can make...
Would you mind sharing:
- What printer you used.
- What difficulties you encountered with the printing process.
- What perimeter/infill settings you used for the strength you wanted, how much filament used.
- Do you have a blog?
Thanks,
-Paul
