Update 0.01 (Jan 2022). Enlarged clearance between bottom and lid hinges. On some printers the two part are to close to each other and needed to be adjust.

The reason to design a storage box is to have all the tools at the nozzles (type V6).
So space for a:
7mm Ratchet Wrench Spanner Fixed Head Mirror Polish 72T Ratcheting High Torque Multitool and a:
Small Cross Wrench Sockets 4mm/5mm/5.5mm/7mm to make it complete.

Hardware used:
1mm wire is used as a hinge rod.

The holes for the nozzles are made to screw them in so they don't fall out if the box is upside down or fell from the table.
