I was looking for led panels to print myself and found the great hexapanels from Bigjim36 (https://www.thingiverse.com/thing:4742593). However, as i was slicing them, I noticed that the housing seemed kinda unstable without the windows and did not offer any mounting options. I ended up completely redesigning the panels and added some new ideas like the outline design or the minishelf.

You can scale the panels up if you want, but not down (100% are 14,24 cm in all dimensions). This will probably look better, and you can install the LED stripes with no effort, that's what i will do next time i print it again, would go for 120%.
