Thanks people for keeping me up to date on 3D printing.
Sounds like everyone is ready to rally round & design*/print a cover for Vince, guess I don't need to bother with what I mentioned on the previous page.
*assuming there isn't already one in the 3DP parts thread.

Oh, please don't let me down, I count on you ! Nothing can beat an original part for... originality !

Even if a 3DP model existed, and even assuming its quality was validated and proved to be a perfect fit, it would still cost more money than I paid for the scope, and it still would look out of place compared to the original part.
3D printing to me is really a last resort. Maybe one day I will have a use case that justifies spending the time and effort to learn CAD, but this day has not come yet.
It's not like I had free time to burn... I have a million long overdue things / projects on my plate in the lab that don't require 3D printing... so these are first...
I wish I were retired so I would have time, but I am only 47 and a house to finish building and an old car to restore and only so many week-ends in a year.. I have to pick my fights carefully...
