I needed lighting and found a 20 cm LED-bar we got from China long ago in the workshop .
The brackets fit nicely onto the upper profile of my Ender 3 and the front claw grabs the LED-bar quite tightly.
A mirrored pair of brackets does the job.
I'd highly appreciate any comment and please post a picture in case you actually printed one of my designs. Thank you!
The circular holes may be challenging to print but besides a little brim to improve adhesion I did not activate any support.
