About this 3D model

This is an entry into the back to school competition. It's a pencil topper that's highly suitable for anybody who loves 3D, a ruler with very thought-out grip for holding the ruler comfortably & a state of the art pencil tray that has 2 compartments with hinges to allow it to move about. Each compartment clicks into each other thanks to incorporated groves on top of bottom compartment & underneath top one. In order to hold pencils in place, the floors of each compartment are in a wavy-like fashion.** hinge side pieces are 3 pieces in 1 model
