Overview and Background
Students were challenged to make an interactive art piece using the 3d printer or recycled material.
Only after 30 minutes two 5th graders had this designed.
Lesson Plan and Activity
Create a box of size dimensions of 28X28X28
Create a box that is the size of 24X24x40.
Turn this box into a hole and put it through the box.
Duplicate this box two more times and turn the one box 90 degrees and the other rotate the other one so it is standing tall on the workplane.
Move these three boxes that are holes to create a cube with holes on all six sides. Make sure the box has the same outer edge. Select all the shapes and group them together.
Create a sphere that is 25 in diameter and place it inside the box.
Make sure the sphere is not touching any of the square. (which is so different on how we touch 3d design that everything has to be touching.)
8 Print using supports and rafts.
