I was about to buy a second wrench to carry out in the field, since I always forget to bring the one from the workbench, but then I remembered I have a 3D printer.

Printed in PETG it seems to be holding up pretty well and hanging up around my neck I haven't forgotten to bring it yet. See Print Settings section for tips on how to customize for your nozzle.
