TRON Backpack

thingiverse

This backpack unit pairs with a disc that matches one from TRON Legacy. The disc can be found at http://www.thingiverse.com/thing:1032216. Small magnets keep it stuck on the base, but a slight pull removes it easily. Assembly starts by printing just the top cap. Next, you'll print either a single unification piece or four quadrant sections that require mirrored settings. Attach all pieces securely, fix any cracks with filler, sand for smoothness and then paint. Install 1/4" in diameter and 1/16" thick round magnets into the holes provided on both the base and disc. Be sure magnet polarities match so units lock together smoothly. A strong hold can be achieved by using super glue to secure magnets.
