Nano Egg

thingiverse

Recently, I bought a Hexbug Nano V2 toy from hexbug.com/v2. The vibrating body and flexible legs enable it to move forward only in random directions, mimicking a large bug's motion. To add some challenge, I created small truncated icosahedron "eggs" using Cheetah3D and printed several of them. These "eggs" provide obstacles for the Hexbug as it navigates its surroundings. Here's a short video showcasing their interaction: vimeo.com/77012228. Enjoy! I later discovered that scaling the "eggs" to 95% before printing reduces jamming issues. To print these "egg" obstacles, I utilized ReplicatorG and a MakerBot Replicator2 with default Replicator 2 slicing settings: Infill at 10%, layer height of 0.200, one shell, feedrate of 40, travel feed of 55, and a temperature of 220°C. A raft with full support was used during the printing process, which only took 10 minutes per 15 mm diameter "egg." The support structure easily snaps off after printing.
