Anyone ever seen the pinewood derby wheels by shapeway in your races?

Look like they'd only be good for show. Razor wheels would still outperform these when rules allow non flat treads.

My thoughts as well for the show cars.. the wheels do have a cool look to them.

And you might by right.. about all the open cut outs in the wheels ngyoung.
It would be like as if you were rolling a wiffle ball down the track.

Those are pretty lovely looking, though. Would be great for a show car.

And if you look at the 3-D viewing option (scroll the thumbnail images all the way to the right), it does not show an outside hole for the axle to pass through!

The idea of 3-D printing some high-performance wheels is intriguing though, and it would not surprise me if some technically oriented Webelo could design his own fast wheels...

I'm not sure that 3D printers have the resolution to get down to what we'd consider acceptable tolerances for wheels. At the very least, I imagine you'd need a turning step for the outside and some kind of boring step for the inside.

Maybe I'm wrong?
