Improved hex key holder V2

thingiverse

Print a O-ring to grip the keys, and this one works well with a 30mm O-ring. It's specifically designed for a standard metric set of 1.5-2-2.5-3-4-5-6-8-10mm. If you need any other size, open the OpenScad file, edit it to suit your needs, and you're done. Alternatively, make a new size with the Customizer - although I've had mixed results with this in-browser app. I printed it in two colors just for fun, and all you need is one printed part plus an O-ring (or rubber band, or spring). This version has the same function as the original, with some minor refactoring to make customization easier. A hole has been added to the middle so you can hang the entire tool set. The logic for placing top labels has also changed - they're now defined by an offset from the holes.
