This was my first contribution to Thingiverse.
I received a Celestron telescope for Christmas (2019) and two of the eyepieces didn't come in a handy protective case so I decided to learn Fusion 360 and make my own. Here is my first upload to the Thingiverse.
The photos are of a version I sliced in Cura 4.4 at "Low Quality 0.28" and printed on my Ender 3. I think they turned out quite nice. Not perfect but it was good enough for what I wanted.
I hope you find it useful.
