We finally charged up the 3D printing pens, made by 3Doodler. A coworker had purchased a complete 3Doodler Start set (the beginner version of the pens, that uses a unique cool filament) and then retired, so I am using them with the students.
The difference? The students loved the pens, though it was really tricky at first….
Here are videos of students (and staff) using the pens for the first time.
