I've been kicking around the idea of teaching either a 3d printing class or 3d design. Attached is a PDF tutorial to design the part pictured. It is a remake of one of the MarbleRun parts I posted originally, except this one is modeled entirely in Fusion 360.

The idea with redesigning the MarbleRun parts is that I know they work, I know the designs, and as the instructions grow so will the complexity of the total parts.

Please feel free to reach out. This is my first attempt at this, there very well could be issues with my methods. If there is any clarification needed, I'm happy to revise it.

I started with two completed projects to see how it goes and if there is any interest.

*EDIT: I found an error while working on the fourth instruction. The Base outer diameter was incorrectly dimensioned to 101.8mm and it should be 101.6mm. It won't effect the part's usability, but I wanted it to be correct.
