Remix of the remix by @percula

I liked this design with the angled sides, because this minimizes the lightloss. The thing I changed was that I wanted the back wall, for less light spill. Also I made it 5mm taller to further reduce the lightspill to where I sit. Then I made the wall of the angled part a bit smaller because this is not really necessary and reduces the (long) print time.

With Cura slicer this print would take over 20h, but with Orca Slicer I reduced the print time to 13h.

I also printed this in esun PLA+ because my previous lights (Redsea ReefLed160) had a shade with the same material for 2 years and never deformed.
