3D Printed Robotic BB8
Introduction: 3D Printed Robotic BB8
Hey everyone, this is my Intructables on how I build my remote controlled 3d printed bb8! By the end I really hope you can feel confident enough on tackling the project by yourself.
Step 1: Supplies Needed
So there are A LOT of stuff needed for this project to make it move, so I'll try to break it up into categories that can make sense. I'll also try and include links to all the items that I purchased
3D printed stuff- Body and Head
1) A 3d printer (this was made to be printed on a smaller buildplate 150x150x150)
2) About 3 kg of 1.75mm filament (odds are it will be around 2 but I'm adding on for screw ups + tests)
2.5) The STL files (given on the 3d printing step)
3) Lots and Lots of time and patience
4) Gorilla glue Gel - I used about 3 bottles for this project. (

5) a rotary tool (Dremel, wen, or anything really) for the friction welding
6) Spackle/Wood Filler
7) power sander + sandpaper (for sanding......)
8) Filler primer (
