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:
