Thank you! I wouldn't have caught that. I'll update my file.>> Here is what your LED-bargraphs look like "BEFORE" and "AFTER" by having one of the slots enlarged by 0.040" or 0.020" on each side of the LED-bargraph itself. On the left is how you currently have things fitting together by using a small hammer to force the LED-bargraph into the panel-slot. On the right, this shows a 0.020" tolerance gap all around the LED-bargraph, allowing it to easily fit through the slot and end up becoming flush with the top of the panel. For reference.....0.020" is about the standard thickness of 3 sheets of standard notebook paper pressed together, with each sheet being approximately 0.007" in thickness.

BTW, were you ever able to able to convert the enclosure to a 3D STL? I'd love to mess around with trying to figure out how I could fit things on the backplane PCB, so if you could share that, I'd really appreciate it.
