This is a box meant to store ten (10) V6-sized nozzles. It uses a print-in-place hinge to hold the top and bottom pieces together and uses 3x2mm magnets to hold them together.

I bought the magnets from here: Amazon.com: 200Pcs Small Magnets, 3x2 mm Mini Tiny Round Magnets, Micro Magnets for Crafts, Miniatures, Refrigerator, Whiteboard : Home & Kitchen

I was largely inspired by this model on Thingiverse: nozzle box M6 by gkx4 - Thingiverse. I mostly wanted to improve on the design by incorporating a print-in-place hinge.
