Neopixel mount for Kossel

__Motivation__
I wanted some nice lighting on my Anycubic Kossel linear plus that would illuminate the object nicely without shining directly in my face when closely looking at the initial layer.
So I quickly designed and made this Neopixel mounting that is a good light shroud at the same time.

__Mechanical__
This is only the _left-hand side_ version, so the little 'cap' sits on top. To make the right-hand side version, simply mirror the model in Cura (or whatever flavor slicer you prefer)
