MUCH BETTER DESIGNED "TECHNIC" PIECES BY EFFERMAN ARE AVAILABLE HERE: https://www.shapeways.com/designer/efferman
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.
