Tron Disc

I created a custom Tron disc with a combination of 3D printed parts I designed, and some electronics. The list of parts is below. Here are a few pictures of the finished product:

3D Parts

Here are the links to the 4 STL files for 3D printing. I used OnShape to design these:

• Center ring (transparent)
• Inner ring
• Shell
• Outer ring (transparent)

Electronic Parts

• LED lights with remote (5 ft, cut to length)
• MintyBoost 3V-5V converter (Adafruit)
  • MintyBoost project pages (solder and assembly instructions)
• AAA battery holder
• Black PLA
• Transparent PLA
• AAA rechargeables

Assembly Hints

• Print 2 copies of the shell (black) and 2 copies of the transparent center ring (C shaped). Print 1 copy of the inner ring (black) and outer ring (transparent).
  • I used tree supports for the shell. Everything else can be printed without supports.
• The MintyBoost requires soldering and assembly. It’s not too bad if you know how to solder.
• Don’t put the MintyBoost into the little Altoids tin. Just hot glue the board into the bottom shell.
• Hot glue the LED lights in around the edge (see the images)
• Screws used to assemble: M2 hex bolts (12 mm), black
• The LED lights come with a remote so you can change the color or pattern
• The AAA rechargeables listed last 2-3 hours — you’ll need to unscrew the shell to replace them, there is no battery cover in this design (sorry)
• The batteries seem to drain on their own even when off, the MintyBoost is suspect
