Lego Mindstorms replacement parts

Oh, yeah, and it would be nice if you post any derivatives that you make.
1. Added the Connector Bush with friction cross axle
2. Made this in the public domain
1. Connector peg with friction tested! I recommend using as small layers as possible, as the print came out very brittle. Maybe this can be a test for print strength? Sorry no pictures... yet!
1. Feedback from the print of the connector peg with friction showed that the inner radius was too much, leaving a brittle print. I adjusted the radius to make it 1.5mm(see the new scad file connector_peg_with_friction_strong to adjust the value if this value doesn't work for you). Anyways, I uploaded the revised strengthened version!

I'm trying to create my own non-lego parts, and I wanted to examine how legos fit together to understand sizes... So I downloaded your part, and put it into Autodesk Inventor to get an idea of the sizes, and I get weird numbers. When I measured my own lego part, I get ~5 mm for the wide top, but when I measure your model, I get either 12.xx mm or .49 in...
Thanks for the comment! It would really be great if you tried printing one of these. I tried to, and got ok results. What kind of printer are you using? I might try to modify the design to make it more stable and printable if you aren't able to print it.

The units are mm.
Not tested yet...
I would like to see this printed, as it would need to be printed at very high resolution.
Upload pictures please!
