Here is another Rainbow Dash, in .1mm translucent blue PLA. The legs and bottom of the tail are actually .3mm by accident, so you can see a little comparison. I had some trouble printing this in ABS, because some of the overhanging perimeters would tend to curl up as they cooled, and begin catching on the nozzle. That might eventually cause a piece to get knocked off the bed, or if the nozzle hit it hard enough, a missed step and offset layers. There were also a few bits of mane or wings along the way that begin above the platform where there is nothing to extrude onto, to the plastic would instead get wiped onto the rest of the model.
I printed this at 175C with the bed at 50C and a 120mm fan blowing over the whole build area. Sliced in Slic3r. Skeinforge kept trying to use too much plastic, making it look messy.
I keep getting requests for Princess Celestia, which hasn't been converted to a printable model on Thingiverse, so I might need to take up that challenge.
