This hot rod model uses the Scalextric4Schools parts pack and is designed to be 3D printed. There are three RP parts in the PTC Creo design; the rear body (blue), front body (red) and V8 engine (chrome). You will probably use a single colour for both body parts and maybe black or white for the engine.
The assembly sequence should go something like this:
Thanks Dan. I really enjoyed modelling it even though it was a rush job for a family day event. It is designed to minimise support material and be easy to assemble. The 3D printer is busy building it as I type, I'll let everyone know how it comes out.
