This is a modification of a design by emiliodc92 on the Sketchup 3D warehouse. I added axles and removable wheels to print it flat. I have included the .skp files if you're interested in modifying it. Download the .STL for the Chassis and wheel. I printed at 1:1 scale, so the VW UP! is approximately 100 mm long. I printed on the Hobbyking Fabrikator on 0.2mm layer with 10% infill using Craftware 1.11 beta with blue 1.75mm PLA filament , and it came out well. To be safe I also glued the wheels on with CA.
