VibroBugs Brush Botsby
These are 3D printed brush (or bristle) bots, a fun take on a popular STEM project. The files include a base, shell and bottom. You will also need a pager motor, batteries and a switch. Full directions on my website, stldenise3d.com. A plain base is included to add your own custom legs. Photos show VibroBug topped with Flexi Rex & Cute Mini Octopus at 75%.
