Solder Holder - T12 Soldering Iron Tip Case

I wanted a sliding case that held exactly as many T12 soldering iron tips I have (11), enough to fit a 10pc set of Hakko T12 soldering iron tips plus one more spot for any tip which may have come with your station.

The photographed print differs from the attached STL and SKP files in that for the STLs I have added two 2mm holes in the top of the tray for a string to make opening it easier, which is not pictured.
