This is a Mokacam mount unlike any other! The Sphero BB-8 pulls his X-Wing and Mokacam around for a video experience that is out of this world! A standard 608 sateboard bearing turns the Rebel Alliance wheel into a fidgit spinner and allows BB-8 to pull his cargo. BB-8 does prefer hard surfaces to pull his cargo.
Here are some videos or BB-8 in action: https://www.youtube.com/watch?v=AnHTDIX1qEQ and https://www.youtube.com/watch?v=c3NWlis5rL0
(Also the rubber-bands are in the picture because the glue is still drying they are not an integral part of the design)
