ASTRONAUT TOOLKIT

ASTRONAUT TOOLKIT

This is a 2-part lesson. In the first part, students are introduced to the brief history of 3D printing in space and ISS (International Space Station) equipment. The lesson challenges students to design their own screwdriver bit or wrench for an astronaut’s toolkit. They will print their design using the 3D printer.
A teacher-led class evaluation of the completed tools follows. Students test and evaluate their designs, discussing what has been learned, what improvements could be made, and what other tools might be useful to have on the International Space Station.
