I further split up the chassis plates on Daniel Noree's OpenRC F1 car in order to fit them on my Printrbot Simple Metal 150mm build plate. I later realized that sections 2 and 3 could be combined and still fit. I have included the file, but I have not printed and assembled that combination yet.
For 4 piece split you would need:
sections 1,2,3 and 4
For 3 piece split you would need:
Section 1, "3 piece center section" and section 4
The screw holes lined up well for me, but the slide joint did require quite a bit of trimming to get it right.
*note - I did not purposefully remove the '"danielnoree.com" emboss from the original chassis files, they were lost during modification in tinkercad.
