1/43 Dirt Late Model Slot Car

thingiverse

I've created a 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 using Autodesk Inventor and Fusion 360, starting with my above 'thing' as a reference point. The chassis uses a standard FC-130 motor (Scalextric can motor) and 3/32 double flange axle bushings. On the rear, I chose 15x8 wheels modeled after hubless CB Design wheels, and on the front, I'm using 14x6 wheels. The printed wheels are okay but don't compare to 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 CB07 on the front). I print everything in PLA, which works well. The chassis and body seem durable enough to last a long time. Hot melt glue is effective for gluing all parts together. Body: Print upside down with the large flat area against the build plate. Supports: From the build plate only Infill: 100% Layer Height: 0.2 Walls: 3 Interior: Print right side up. I modified my g-code to change colors at the point where the roll cage starts printing. Supports: None (The roll cage will be a bit stringy, but it's too thin for supports.) Infill: 100% Layer Height: 0.1 Walls: 3 Bumper: Print upside down with ends of 'tubes' against the build plate. Be careful when removing supports as the tubes can easily snap. Supports: From the 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 right side up. I just use a marker to color the top surface black to look like a lid. You could also change filaments on this one if you wanted. Supports: None Infill: Doesn't matter Layer Height: 0.1 Walls: 2 Top: Print upside down. Supports: From the 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 different print orientations and settled on printing it vertically. 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. Supports: Everywhere Infill: 100% Layer Height: 0.1 Walls: 3 Chassis: Print right side up. Supports: None Infill: 100% Layer Height: 0.2 Walls: 3
