Slot car chassis Marcos 600 LM, Fly

This is my first project in 3d, as my favorite hobby, the slot cars, are important to me, so i,ve tried to design this 3d chassis for the Marcos to get the best from it, and you'll be impressed,
i use a standard slot it or scaleauto motor support, and you have to arrange a new cockpit, cos the original is to narrow, I've made one in lexan.
The STL file it is not the final work and it doesn't fit
Soon you can look for it in Ebay as others, that i already made.
