This is a somewhat experimental model, for testing different sizes of pinholes. This one is 2.44 radius or 4.88 diameter.
EFFERMAN HAS HIS OWN, PROBABLY SUPERIOR VERSION OF THE 2x2 BEAM HERE: https://www.shapeways.com/model/2778744/2x2.html?materialId=6
He created it at my request. His model isn't as nice looking, but it is probably more functional.
Unfortunately, shapeways prints seem to be too chalky to notice any difference so far. The holes are still too tight. You may have better luck printing these yourself.
YOU MAY DOWNLOAD THIS AND PRINT IT YOURSELF. I release this design, copyright free, into the public domain. I am also hosting the sketchup file on my own website so you can download that too if you want to make modifications: http://taranvh.com/wp-content/uploads/sites/4/lego
THERE IS 0% MARKUP ON ALL MY PIECES - My goal is to create enough interest and demand so that the lego group starts making these.
