My tricycle arrived today! The wheels and pedals turn beautifully, the only thing that didn't work is the handlebars, they seem to be stuck in place, there must still be support material in the shaft connecting the front assembly to the main chassis. Any tips on how to remove powder from hard to reach areas? (EDIT): I did some gentle back-and-forth motions to the steering column, and it loosened the powder, so now the steering works perfectly. It's not as loose as I like, but good enough for now. http://www.shapeways.com/model/150737/tricycle.html?gid=ug42 47 Video of it in action coming soon!
