3D Printed Marble Run Parts

The 3D printed parts were used to create a marble run. The parts could be attached to a peg board along with other materials to create a course for a marble.

• Autodesk Fusion 360
• Ultimaker Cura
• Ultimaker 3D Printer

Fusion 360:

1. Create the sketch of the arc piece
2. Use the sweep tool to create the back edge of the part
3. Use the extrude tool to make the two sides and the hole (where a dowel can go)

Fusion 360:

1. Create sketch as shown in the picture
2. Revolve the sketch
3. Use sketches and the extrude tool to create a flat part on the funnel
4. Sketch and extrude two cylinders to fit into the holes of the peg board

Fusion 360:

1. Create sketch as shown in the picture
2. Extrude the rounded section of the wall
3. Extrude a flat wall on the back
4. Extrude two cylinders on the back to fit into the holes of the peg board.

Fusion 360:

1. Create a sketch
2. Two circles and a curved line (make the smaller circle the size of the pipe you want the piece to fit on)
3. Use the sweep tool
4. Extrude a section off of both sides of the piece so that the pipe will easily fit

Fusion 360:

1. Create a sketch of a curvy line
2. Use the pipe tool to turn the line into a pipe-like piece

Fusion 360:

1. Click file, then 3D Print
2. Select your piece or pieces
3. Use the 3MF format
4. Download your piece

Cura:

1. Place your pieces from the download folder
2. Format them in a way that uses limited supports (see picture)
3. Change printing speeds
4. Change support structure to tree
5. Slice it and 3D print!

Put your 3D printed parts on a board to create a marble run! The pictures show some examples of what people made with the parts.
