Star Wars Rolling BB-8 Droid
All of my full scale props droids that i build so far are with foam and reinforced with craft sticks. For this particular project , everything is 3D Printed. After two different spheres, the current sphere I used is Vonjet Sphere; a unique unibody with no inner skeleton panel. As for the drive , I have made 3 different versions of my own which all end up in disaster. Now, i have 3 sets of different motors and parts collecting dust. I decided that im not cut out to design a complicated mechanism and get a rolling proven design instead. Both Vonjet Sphere and Joe Drive is available for download at BB-8 Builder forum.
Balancing a 300gram dome on top of a rolling 50cm sphere is not easy task. If you are making your own, prepare for lot’s of work and headache xD . If you want a head-start with your own project, my personal BB-9E sphere is available in the shop.
