Why I need this: I do several 3D printing projects with my at-risk students to teach scale, modeling, and problem solving. Currently we borrow a 3D printer from a neighboring school. It will be more manageable to have our own printer to do these projects and expand our 3D printing options.
Why I need this: Well, you can't use a 3D printer without filament. I chose white so that once a model is printed, students can color it in anyway they wish using sharpies and/or paint.
