Designed to fit trofast boxes from Ikea to keep them closed in my car during road trips. For small boxes 2 to 4 clips are sufficient but large ones require up to 6 to be closed securely. Clips must be fitted bottom first and then pressed onto the lid to be secured correctly on the bottom plastic lip of the box. The hole on top is there so you can pass a little rope or elastic to prevent the misplacement of the clips or to secure things on top of the closed boxes.

Both .STL and .ipt (autodesk inventor files) are available.

Remixes, suggestions and improvements appreciated ;)
