Need to re-print the interior as the clear filament I used printed roughly and is too brittle. Will buy some white for the job I think. VERY happy with the design and how it went together. Steering servo is fitted, but yet to buy a motor for it. Tyres (temporary but I think they will work), are cut from foam pipe insulation from my local hardware store (Bunnings) - 1 1/4" ID x 3/8" thick. Printed on a 3D StuffMaker evolution with a 0.7mm nozzle.
