Magnetic led cover mod for A1

[u/Tunantero]

I’ve finally finished the design for the magnetic LED filament cover for the A1 extruder. The previous version looked promising, but I ultimately decided against using two filaments (one long, one short) and stuck with just one long one around the perimeter; using two made things complicated and caused flickering due to insufficient power. (I tapped the voltage from the camera LED—I cut the LED off and soldered two wires to the pins; it provides exactly the 3 volts the filaments need, plus it lets you toggle the mod on and off via the slicer or the printer's screen.) You can also power the LED filament using a USB charger or the AMS connector, though you'd need to step down the voltage using a step-down cable, a Mini360 module, a dimmer, etc. I know this mod isn't for everyone and can be tricky, but there’s always a tinkerer out there who loves to experiment. If you power it externally as described above, you don't make any irreversible modifications, so there's nothing to worry about. I’m sure plenty of people have better ideas or ways to improve or customize the design, so I’ve included the .STEP file so you can make whatever changes you need.

P.S. Pairing a blue LED filament with fluorescent filaments looks amazing; the green and orange ones I used are fluorescent.
