Marble Machine Spiral Coil

I am learning Fusion 360 and made a simple marble run.

The marble machine is designed for 9 mm marbles. I suggest scaling for any other size of marble. The top cap is a little tight already so that the machine doesn't come apart while playing. Be careful when scaling down.

Make sure to flip the handle and top cap stl's upside down before printing.

The corkscrew has a small profile. If you struggle with adhesion, use a brim for that part.

If you use cura, I suggest printing the actual track using the seam at sharpest corner setting.

The best part is that you don't need supports! The steepest overhang is 60 degrees. I got it to print just fine with my 0.8 mm nozzle. It should be a much easier print with a small nozzle.

Have fun!
