Simple LED light bar for better visibility of printing in the evening. It requires a bit of skill, but you can make two variations. The second is for the experienced as you'll be working with high voltage components, the first is easier with just the parts you probably already have lying around at home. It's not perfect, but it's about the only place you can effectively place an LED strip in a neat form.

Printed parts:

I have prepared .3mf files with supports, but you can try other print orientations (I have no luck with the lay on top orientation, try it yourself if you want, I'm probably an idiot). Don't print with PLA, especially the light bar part, because the LED strip produces heat. I used transparent PETG. For aesthetic reasons I recommend only 60 mm/s and 0,16mm layer height.

Hardware:

You need one screw, I specially modified the model for the PC fan screw that all of you already have somewhere.

Aluminium profile, max 12mm wide, cut lenght 168mm

Electronics:

12V LED strip, COB variant will produce the most light, so use it, cut length ~150mm

Assembly:

Easy variant - some 12V power supply, power doesn't matter, you probably already have one at home (old router etc), it only requires soldering to the LED strip and a switch between the PSU and the light.

Pro variant - LED driver with constant current, 3-5W, it's super cheap and fits easily into the top cover (don't forget to use the bottom cover!!!). And a power cord with a switch.

If you find anything wrong, or have ideas for improving this light, feel free to comment here :) I also added .step files.
