Go-Kart Track

                                                                !!WARNING!!

         This design has not been tested before. There is a risk that it may in some way fail.

Instructions:

First, print all of the pieces. While only the track connecting chips, the pit stop, and the road blocks have pre-sliced G-Codes, I have listed the recommended settings below. 

Recommended Settings:

1. Top and bottom fill pattern (optional for looks though will increase print time dramatically): Concentric
2. Perimeters: 2 or 3 (3 for good measures)
3. Infill pattern: Gyroid
4. Infill Density: 10%
5. Layer Height: Whatever you prefer though I recommend 0.25 to reduce time.
6. Color change (optional for a nice distinction between the side walls and the track itself): At 4.20 mm or so that the track is a different color then the borders or side walls. Additionally, suggested colors include gray for the track, black for the border, gray or the same color that you used for the track for the track connecting chips, yellow for the movable blockades.
7. Brim: None
8. Supports: None
9. External Perimeters First: No

Second, after you have printed all of the pieces, refer you'll have to assemble them together. Basically, they get connected by gluing the track connecting chips to one track piece and then another and then the tracks will get both aligned and connected. Additionally, if you cannot tell how the track pieces line-up by the picture above, I have created a system. Basically, each stl is named “Part” and then a number. That number then corresponds with a diagram that I have included below. That way each piece is assigned a number and each number has a position.

Third, and probably the most important step; print a go-kart, race car or use a car that you already have. I mean, if you spent all this time making it, you have to use it. If you don't already have a car that you like, I included a link to a go-kart that I personally designed and it's proportions are set for this track.

Finally, I'd love if you could post a make.

Happy printing and racing!
