I <3 3D pencil topper, flexible pencil tray & ruler

thingiverse

This back-to-school competition entry features a pencil topper with a 3D design and a heart-shaped cube. The innovative pencil tray starts as a cubic block, transforms into a rectangle with chamfered edges for smoothness, and boasts inward extrusions that click neatly into place thanks to inward grooves created using the Connect tool. A special grip is added to the ruler, which also began as a cube before being shaped into a rectangular design. Hinge side pieces are made up of three components for a streamlined look.** The pencil tray's hinges feature cylindrical shapes.
