Ha, thanks, I was referring to it's ability to export something usable by openscad.

My googlefu is not THAT bad...

Hole is for 5mm shaft for NEMA 17. The clamp feature is sized for #8 Machine screws as I have access to a multitude of SAE sized screws/bolts and not metric.

Solidworks web page is here http://www.solidworks.com/

I'm quite happy with it but it is expensive, $6,000 to 10,000 depending on the version you get.

The student version is in the hundreds though.

What machine did you use to print the one in the picture? Not quite makerbotable, I just ended up with a solid cylinder. Have you ever used openscad? A parametric file would be handy so you could have different sized shaft openings.

I modeled it in Solidworks and printed it on a Dimension SST1200ES. It's a soluble support machine, so overhangs are not an issue.

I would post pictures, but the license you chose doesn't allow me to "I made one".

I'm giving it a 2nd shot, it seems like the key to printing these gaps on a makerbot is to have it laying down on the bed.
