Thank you, tart2000, for making this lovely LEGO Ring on Thingiverse. My son had a great time adding the bling!
Thingiverse link: http://www.thingiverse.com/make:65858
Settings: MakerWare .3mm/low on a Replicator 2, with no raft or supports.
Technical notes: We made this from tart2000's "less chunky" demo file without any changes or customizations. At first we thought the 2x2 LEGO plate was not going to fit in the ring, but a set of pliers told us differently. The tight design makes the ring really secure, and it is easy to add and remove things from the ring without the plate falling out. A simple, elegant design that just works!
