With permission of the original creator, I modified his tower shield to have slots for LEDs and holes for wiring.
Edit: In testing, I discovered that the original tower was too tall if you use the P5 full bed calibration. Just uploaded V2 which is short enough to clear the arms at full extension.
While I was editing, I made a variant that covers the LEDs so you can print with clear filament and it'll act as a diffuser.
0.014 but anything should work.
Shouldn't need supports, only minor bridging... Check Retraction settings first or you might have to carve out the LED slots.
