This is a box i designed to store 2 types of air rifle pellets but is suitable for anything small. I printed another one to keep electrical components I have spare like LEDs, Transistors, Capacitators and resistors. Scroll down for images

How to assemble:
The box might need some cleaning up using pliers and sanding paper for it to close and open super smoothly. To assemble the box, place "PelletboxCover2" on top of "PelletboxDesign2"
(Make sure the guides are the right orientation)
and test for it to slide open halfway both ways to reveal one side of the box.
Afterwards, take "PelletboxCover1" and attach onto the box.
"PelletboxCover1" acts as a safety lid in case "PelletboxCover2" falls of due to its decreased size for easier movement.
Images attached if still unsure.
