Game Plan

The MC2 STEM High School Fab Lab serves as a practical laboratory extension of classroom theory. The Lab is equipped for all phases of woodworking, metalworking, and machining, as well as digital fabrication with CNC routing, laser cutting, and 3D printing. The lab is available to all MC2 STEM High School Faculty and Staff, as well as community members interested in making and design.

We will explore several of the machines in the Fab Lab including the Epilog Laser Cutter, 3D Printer, and the CNC Shopbot spread out over 6 days for a total of 15 lab hours.

Kickoff Challenge

Make a 2” x 2” x 2” cardboard box with the following tools:

Cardboard

Pencil & Red Pen

Ruler

Hot Glue guns

1. First sketch your layout using a pencil and the ruler
2. Redraw each line that you are going to cut with a red pen.
3. Use the ruler to make a straight edge and cut carefully with the exacto knife.
4. Assembly with hot glue

Check your measurements, is each piece 2” x 2” x 2”?  

What is the total surface area of the box?

What is the total volume of the box?  ***

Lessons:

• How to properly use an x-acto knife (cut 3 times, have something underneath)
• What good cardboard looks like? And what to throw away!
• Not everything requires a laser cutter!
• Lasers like X-acto knives like to cut on Red lines -not really, but it helps to know what you want to cut and what you want to etch
• Material thickness often gets overlooked when designing for 2D to 3D assembly
