Summary

This was an early Tinkercad drawing for me that I finally got around to finishing.

The idea is a little Necron "Greater Summoning Core" from Dawn of War to be used as a light for the power and drive activity LEDs of your desktop computer. Or just as a little lamp if you'd like. Or terrain even.

You'll need one of everything, four of the circles. Optionally the "baseplate" part if you want to use 5mm LEDs instead of sticking a piece of LED strip on the sides. I had contemplated this but the soldering work was easier for just using some leftover strip pieces, so ultimately didn't use it.

I printed the components all in white to be reflective and spray painted the outside of them with some Army Painter Matt Black primer, then touched it up with some matte paint. The "framework" piece needs to be printed with a translucent (ideally glow-in-the-dark) filament if you intend on using it as a light.

The top and bottom pieces will be really easy to line up and glue in place. Use the spacer to align the middle pieces as you glue them in to place. It also works for centering the circle pieces.

I suggest using a gel CA glue as it will take a few seconds to set, giving you time to get everything lined up nice and neat.

I took a voltmeter to my PC's LED pins for power and drive activity and saw 5v for both, so I just used some 5v LED strip pieces so I didn't have to worry with resistors. I think a single segment of green COB LED with a few pieces of UV/near-UV connected to power with a second green strip for drive activity would work best - I wired mine up using green for power and two UV for drive activity and it's a very subtle effect. The intent of the UV LED is to charge the GitD filament so when you put your computer to sleep the core glows for a little while. It's a bit underwhelming and the wavelength of green light is terrible for charging glow in the dark material. Alternatively you could use white LEDs and a green filament, as the framework walls are only 0.8mm thick. I'm curious to see what you come up with! I crimped on some DuPont connectors and plugged it in, dressing the cables away underneath the tower.

WARNING: Not all motherboards are equal, so I encourage you to carefully test yours with a voltmeter first and if necessary add resistors to prevent any damage to your computer!
