SERIOUSLY, DON'T BUY ANY OF MY PIECES, HIS ARE MUCH BETTER!

On all of my models, the pin holes are currently too tight. They can hold pins GREAT, but axles and friction-less pins will be greatly hindered by friction. Also, even Shapeways' polished plastic is still too chalky - you may have better luck printing these on your own. ----- All of my 3D models are in the public domain, so you can modify, print, or do whatever you want with them: http://taranvh.com/wp-content/uploads/sites/4/lego/ There is 0% markup on these pieces.
