Metric Allen Wrench/Hex Key Set

The combined stl includes 12mm, 10mm, 8mm, 6mm, 5mm, 4mm, 3mm, 2.5mm, 2mm, and 1.5mm. Each are available individually along with a 7mm. They might not be that great for practical use since the smaller sizes will be a bit weak and it's likely the prints won't be quite to spec depending on things like your nozzle size. The included .scad file allows for custom wrenches to be generated with variables for thickness, short and long arm length, and the bend radius.
