1/32 Dirt Late Model Slot Car (body and chassis)

Description

Original design dirt late model body and chassis for 1/32 slot car racing. I designed the parts using Autodesk Inventor and Fusion 360 from the proverbial "blank sheet" just to see if I could come up with something workable. It turned out better than I expected so I wanted to share it here (and in the forums at homeracingworld.us). I started the design using the dimensions from a Craftsman Late Model Series rulebook I found online (no idea if they were the current rules or not). The final car is not exactly to the rulebook, but it's pretty close to true 1/32 scale. Body and chassis were designed together so the fit really well with each other. The chassis uses a standard slot.it inline motor pod. I found that printing the body in multiple pieces and gluing it together gave me the best results. I used hot melt glue with very good results (so far). There are two version of the body and chassis, 2 post and 3 post. The 3 post body has two mounting post locations in the front and one in the rear (which on you print is personal preference, just make sure to print the matching body/chassis). 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. 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: 0.2 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: 0.2 Walls: 3 Hood: print right side up Supports: none Infill: 100% Layer Height: 0.2 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: 0.2 Walls: 2 Top: print upside down Supports: from build plate only Infill: 100% Layer Height: 0.2 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. Supports: everywhere Infill: 100% Layer Height: 0.2 Walls: 3 Chassis: print right side up Supports: ?? I usually print with supports, but I'm not sure they are really necessary except under the guide area. The supports under the guide area usually have to be sanded off with a Dremel. I never printed one without supports, so feel free to experiment and let me know how it works.
