An ultra slim monitor led light bar. It uses 3mm cob ledstrips and a touch sensor to control the brightness.

Additional parts used:

• DC12v 24V 6A Dimmable Sensor Switch (I got the big spring version)

• 40cm of 3mm cob led strip (cut into two 20cm lengths)

• DC 5.5mm connector

• 4 M3.5x16 tapped screws
• Some wire to connect everything

How to print:

Please check the photos for the one with the buildplate. You can see only “lightbar-part1.stl” needs a bit of support. The rest is designed to be printed support-free.

I also did not need a brim, but you could put it on for safety since the parts are pretty narrow and the ends of the lightbar-parts could potentially lift from the bed.

Rest of the print-settings in 1.75 PLA with 0.4 nozzle:
