Treasure box pencil case
thingiverse
This pencil case has hidden compartments, revealing different storage areas as buttons are pressed. The key-shaped topper on the pencil reveals a ruler compartment, which then opens to store erasers, lead, paper clips, and more. A spring mechanism within the case lifts the top when the button is pushed. All parts of this innovative design can be printed without external components; however, a prototype has not yet been created. The inventor tested the spring and pivot pieces through printouts and shared a video for a visual demonstration. This is a first upload to Thingiverse, so feedback is welcomed. If you have questions, feel free to ask! ### Example
