Thats my baby.... or maybe 2nd kid once removed....
I know I have a few requests for the body - so I will post a link to the PDF file here - and on facebook... and on the shapeways page. The body is paper..... I did that A) to keep the cost down and B) at the time - I thought it would be fun to have a kid color it in etc.....
Sorry if I haven't responded recently if you emailed me... a lot going on - on and off the track so to speak...
Most guides will fit - slot.it, scaleauto, slotting plus etc...
Basically you need the guts of a scalextric F1 car to get it going (or equivalent new parts)
The motor is very tight fit - on purpose - so it needs to be shoe-horned in with a small flat blade (careful not to squeeze it in on the cage... Squeeze the frame)
This is the body - though the template is just an outline with the pipes...
