This is a case I made to hold my D60 Soldering iron, the USB C power supply with cable, an extra tip, and a desoldering pump.  It uses the Allen key (that is needed for the tip exchange) as a hinge.

I wanted the case kept small(ish), so I decided to put the soldering iron on a separate level in the case.

The photo is from an older version of the case. The model is a newer version that has the tip moved closer to the desoldering pump to make room for additional stuff under the soldering iron, such as solder and a sponge. The case uses 5mmx2mm magnets to keep the lid closed: 6 for the top lid and 4 for the bottom lid (secure the magnets using super glue or epoxy glue)
