It was designed with the intent of putting [LEDs](https://www.amazon.com/gp/product/B012FFYKC6/ref=oh_aui_search_detailpage?ie=UTF8&th=1) powered by a [Lipo battery](https://www.amazon.com/gp/product/B014IJEQ8K/ref=oh_aui_search_detailpage?ie=UTF8&psc=1). The files as is are my best guess at what the scale of the actual disc in the game is, about 276 mm in diameter when assembled. You could of course scale it down to make it faster to print as long as you scale all the parts equally.

To build a light up version, you would print:
* Laser cut center.dwg from 1/8" thick acrylic
* edge.stl needs to be printed 8 times, twice as is, twice mirrored X, twice mirrored Y, twice mirrored X and Y
* middle.stl
* middle_withbatterydoor.stl
* batterydoor.stl and 4 batterydoortab.stl, the battery door tabs are
