Mach 5 car from Speed Racer cleanup

Last crawled date: 5 years, 7 months ago

I liked Gadmek's version of the Mach 5, but the file had several errors I had to fix.

I've also added support for the steering wheel so it will print at this size. Previously it would break off while trying to remove supports, it simply printed out too small/thin
