1/43 Dirt Late Model Slot Car

See also my 1/32 version of this car: https://www.thingiverse.com/thing:3415449 Dirt late model body and chassis for 1/43 slot car racing. I designed the parts with Autodesk Inventor and Fusion 360 using my above 'thing' as a starting point. The chassis uses a standard FC-130 motor (scalextric can motor) and 3/32 double flange axle bushings. On the rear I chose to use 15x8 wheels modeled after hubless CB Design wheels, and on the front I am using 14x6. The printed wheels are okay, but nowhere near as nice as a set of aluminum ones. Find the smallest tires you can for a good fit (I used Super Tires 1400 on the rear and QuickSlicks CB07on the front). I print everything in PLA and it works well. The chassis and the body seems to be durable enough to last quite a long time. Hot melt glue works well for gluing all the parts together. Body: Print upside down (large flat area against the build plate) Supports: from build plate only Infill: 100% Layer Height: 0.2 Walls: 3 Interior: Print right side up. I modified my g-code for a color change at the point the roll cage starts printing. Supports: none (the roll cage will be a bit stringy, but it's too thin to use supports) Infill: 100% Layer Height: 0.1 Walls: 3 Bumper: print upside down (ends of 'tubes' against build plate). Be careful when removing supports as the tubes can easily snap. Supports: from build plate only Infill: 100% Layer Height: 0.1 Walls: 3 Hood: print right side up Supports: none Infill: 100% Layer Height: 0.1 Walls: 3 Air Cleaner: print ride side up. I just use a marker to color the top surface black to look like a lid. You could also do a filament change on this one if you wanted to. Supports: none Infill: doesn't matter Layer Height: 0.1 Walls: 2 Top: print upside down Supports: from build plate only Infill: 100% Layer Height: 0.1 Walls: 3 Spoiler: this is the hardest one to print because it's so delicate. I tried several different print orientations and settled on printing it vertical. Vertical takes the longest, but makes a nice looking part. Be extremely careful when removing supports (there is a lot of support material in this orientation) as it will snap at the 'end plates' very easily.
