Summer Camp Project

The members of Texas A&M University’s AggieSTEM program have invited me to bring SOLID Learning elements of 3D printing to their Summer Camps this year. I am considering our Projects for the classes, as the format will be a Project Based Learning engagement intended to create a useful end product the participants will learn from in other settings after the summer camps are over. The sessions will include one teachers-only and two teenage-participant groups.

The latest MAKE magazine (volume 39) has a cover example of a 3D printed projectile for spud guns that will carry a GoPro camera aloft to capture video from high above the launch area. This GoPro Cannon Cam project seemed an excellent possible project for our summer participants, since the end product be used in later Physics lessons illustrating ballistic behaviors, Mathematics lessons addressing chances measured against time of flight, and even Wildlife and Resource Management studies of the area around their schools seen from far overhead. Components

To test the time required to build one of these projectiles, students who have not yet left for Summer events printed out the components using surplus natural ABS filament from our Project Egg support project earlier this year. I discovered the designer of the Cannon-Cam projectile left out the slip rings (2x) from his STL archive on the MAKE magazine site, so I created the missing design item and shared it on Thing-i-verse (http://www.thingiverse.com/thing:336517) for others who want to build their own projectiles.

FinsAfter the workshop participants got involved the smaller pieces like the cut-off brass rods and torsion springs went in pretty well. The final design lacks only the GoPro camera and its window protector, and we will build the cannon itself in weeks ahead! Once that is completed, we can get permission to discharge the projectile on the campus grounds and see if the Summer Camp’s sponsors like the project deliverable!
