MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
anything which is marketed for use on skateboards or rollerblades is likely to work well. Unfortunately, they are going to cost $1.00 to $1.25 each instead of $0.30 each (50 for $15 deals).
The ones used in the video are "rollerbones" that I got from amazon as an 16 pack for $23.38 ($1.46 each).
