For the classroom, workroom, or bedroom, most of us have pencil/tool boxes to store and transport our accessories. Most pencil boxes often have zippers or hinged covers that take up space when you open it. As we students keep growing up, school desks become smaller and smaller, and space is definitely limited.
With an increasing public interest in 3-D technology, we wanted to make our design easily 3-D printable. That means, in the design, there would be as little unsupported parts or hanging parts as possible. Also, we wanted the design to be as simple as possible. We also wanted to make it a suitable size for a typical school desk, so the pencil box size would be about 6 in. by 2.5 in., about the size of a Ti-84 calculator.
Step 1: Design
The lid contains a ridge that locks into place with the indent on the sides of the pencil box body. This allows the lid to snap shut. The 4-in. long ridge allows the lid to slide in and out of the 4-in. long indent. In addition, the indent is centered between the top and the bottom of the pencil box body. This allows the lid to fit perfectly when both open and closed and allows the pencil box to take as little space as possible. The design is also simple and doesn't contain any hard-to-print parts.
