Mini Racer

thingiverse

The Speedster is fast, compact, and fuel-efficient. An aerodynamic design and minimalist take on suspension enable it to reach maximum speed across hardwood or linoleum flooring. Its modern styling set this 3D Printed car apart from other toys that often end up under the couch. JD Power and Associates have never heard of the Speedster, but if they ever do, they'll likely print one for themselves and display it next to their trophy. I designed this toy for my son and his Little People City Skyway. We needed more cars, so instead of buying them separately, we designed and printed our own. Design your own with the Speedster OpenSCAD library. To assemble the speedster, print one of the three bodies, four wheels, four hubcaps and two axles. Snap the hubcaps into the wheels. Insert the axles through the holes in the body and attach the wheels. I prefer to print the body and hubcaps in one color and the axles and wheels in black. The cars pictured were printed on a MakerBot Replicator 2 at 0.2mm resolution. I used Simplify3D to arrange the components and added supports manually to the wheel wells. All parts use 10% infill, except for the axles, which require 100%. If you want to customize a speedster, clone the Speedster repo, download and run OpenSCAD, open racer.scad, and follow the instructions.
