Modeled in Maya while sitting at a coffee shop near Stanford (man did I feel like I fit some sort of stereotype). After working on "Geo Necklace 01", I wanted to try something slightly more complicated. This "bracelet" is two combined tori: The base is 8-sided, the top is 6-sided. No overhang issues, but I did have to pick out some interior loose filament. Spray-painted it two-tone blue/red.

Successfully printed in 'natural' PLA with "medium" settings in Makerware:
*Extruded at 210, HBP off, no supports.
*2 shells, 10% infill (presuming there is any infill at all).
Took 50 minutes to print, used 13g of PLA.
