I recently built the Sega Neptune from scratch using cosam's PCB. When I tried fitting the Genesis 2 shell with the RGB LED, the light pipe was blocking the shell from closing. The RGB LED is bigger than the original, so I made a 1:1 model of the original lightpipe but shortened the length so it would fit properly. This is in 2 pieces for easier printing since the base is locked into the shell, the smaller top won't come out.
I've added the 3mf file with my print settings. It's just the Bambu Transparent PETG profile with the models in it. It printed very nicely but is slower.
The author marked this model as their own original creation.
