Sphero Shell

After several years, I finally decided to play with my Sphero Sprk again. Unfortunately, the batteries were completely dead, so I decided to replace them. Because the shell is waterproof, I cut it open, made replacement shells for it, and wanted it to include the original symbols. I printed it just 1 outer wall to see the lights better. I´d recommend gluing it together. This is my first design here, I hope that you guys like it!
