Conventional finger skateboards may be the accepted present-day method of boarding with your fingers, but here on Thingiverse the future is now. Hop your digits onto this Finger Hoverboard, and float along in style!
Not guaranteed to work over water.
The hoverboard in the photo was printed in Stone and Stellar Pink MakerBot ABS, "magnets" down, with a raft and support. If you keep an eye on the print, you can pause it and swap colors between the magnets and the board like I did.
This was made without any traditional modelling software. I scaled the board from lsapozhnik's Finger Skateboard up to 100 mm long in MakerWare, then added some suitably scaled helper discs to serve as the magnets. I then exported that as a new STL and ran it through netfabb's cloud service which removed the screw holes and made the shape one solid piece.
