If you are like me and your favourite book is Hover Car Racer by Matthew Reilly, then you will love this.
Designed on Sketchup, it is a concept idea of Jason's Argonaut, complete with seats and magneto drives.
If I win the 3D printer, I will undertake the challenge to print a prototype and also print different hover cars like the Marseilles Falcon and the Ferrari F-3000. If all goes well, I will propose to move it to commercial manufacture and also open-source the plan online for you to modify and experiment to your heart's content.
Thanks and enjoy the images!
