This is a 3D model created on Solidworks, by surface and solid manipulation.
The idea of this model was for me to practice on the surface manipulation on Solidworks, but I ended up printing a scale model of the design.
On the zip file you will get 3 STL archives. The main body has 4 pins to hold the wheels. You'll need to print a pair of back and front wheels, to get the 4 wheels of the model.
Back wheels are bigger than the front ones, therefore I make'em on separate files.
The first model I printed was on a Fortus 250mc, with a resolution of 0.007in.
By petition, I'm adding Solidworks and STEP files, if anyone wants to play around with the model.
Have fun, and enjoy... =)
