Echo Arena Disc

thingiverse

The disc from the best multiplayer VR sports game, Echo Arena, was designed to put LEDs powered by a Lipo battery to good use. Original disc model courtesy of Echo Arena player Exhibit. It was created with the intent of bringing LED lights powered by a rechargeable Lipo battery to life. The files provided are my best guess at what the scale of the actual disc in the game is, about 276 mm in diameter when assembled. You can easily 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'll need to print: * Laser-cut center.dwg from 1/8" thick acrylic * Edge.stl needs to be printed eight times: twice as is, twice mirrored X, twice mirrored Y, and twice mirrored X and Y * Middle.stl * Middle_withbatterydoor.stl * Batterydoor.stl and four batterydoortab.stl. The battery door tabs are super glued to the battery door. This allows you to place the battery door into the hole of center_withbatterydoor and rotate it so it stays in place just from friction. * Small registration circles are on the bottom of each edge piece, so glue them into place. I used E6000 to avoid the super glue ghosting / fog on the acrylic * Glue the LED strip to the inside edge of the laser-cut acrylic * Use two pegs to align the two middle pieces and glue them in place To build a non-light-up version, you can replace laser-cutting center.dwg with just 3D printing center.stl instead. And you would print two middle.stl instead of printing the battery door one.
