Dash and Dot Robots Trailer
thingiverse
They're robots from Wonder Workshop that come together in one of their kits. Dash is the bigger one that can move around on its own, while Dot is the smaller one with sensors but no moving parts. My daughter wanted Dash to pull Dot along, so I came up with a simple trailer that lets them travel together as a team. You'll need some super glue and 2 skateboard bearings to get started. Everything was designed to print without any supports. The Dash and Dot connectors are based on the design from https://www.thingiverse.com/thing:3321647, but I completely re-designed everything else in Tinkercad.
