Awesome design to improve the visibility while printing.
I printed the bottom part in transparent PETG and installed LEDs on the top so the nozzle gets some light.
LEDs - metric size 3014 (3 x 1.4mm), cold white
Resistors - size 0603, 390 Ohm
All LEDs have a Resistor attached and are wired in parallel using thin uninsulated copper wire.
At the back I've added two cables to the spiral wrap and they connect to the copper wire.
These cables are connected to the 5V and GND pins on the EINSY board.
Added Color change after the bottom section to switch to black PETG.
