Recycle the spindles for blank CDs/DVDs into stands to display models, or really anything. I designed this to display 1:100 Master Grade Gundam / Gunpla models, but it could be adapted to a variety of uses.

The arm part is designed to be "stackable" so that several arm pieces can be attached together - either as multiple stands off of the base or as pivot joints extended off of the arms. See the several images with this thing for examples of how it can be used. It fits an American/Imperial #8 hex nut and screw, and I'm sure there is a metric size that will fit too.

The part was designed in Sketchup, repaired in Netfabb Basic, aligned in ReplicatorG, sliced with Skeinforge and printed with Pronterface on a Solidoodle 2.

Print a "base" piece, and as many "arm" pieces as you want. There are 2 different STLs for the arm, printing it either flat on the bed/raft or upright. Printing it flat will get a smoother curve on the round part of the arm but will require support material inside the arm's channel which will have to be removed before the part can be used. This orientation is also weaker as the layers are lengthwise to the part. Printing the arm upright means a stronger piece and no support material inside the arm's channel, but the curve will end up rough and need to be cleaned up with a file or hobby knife before it will interlock with the base or other arm parts.
