I need access to a 3D printer! If you love Legos, K'Nex and Tinkertoys, then you you have a similar need. The folks at F.A.T. Lab and Sy-Lab just developed items you can print out for free via your rapid prototyping 3D printer which allows these three building / construction toys to be interconnected. How cool is that?! Here is the link to download your designs / free universal construction kit!
If you have some engineering prototype designs in the queue for your 3D printer, they can wait. This is really important!
Post Update on April 13th: I'm investigating the online 3D Printing Service named Shapeways. I uploaded some of the models, but I need to find out if the design dimensions use metric or inches.
