A simple Chicago Cubs LED Sign!
Highly recommend you print with the attached profile. Definitely using Arachne for walls.
!!! Be sure to remove calibration lines before letting print continue !!!
I used a simple USB powered sticky LED strip for light. Added some hot glue to the hole where the LED power cord goes through the back to keep it in place. I've found it helps if you put your LEDs down the walls closer to the back. It helps prevent individual lights shining through.
