parametric Hex keys
thingiverse
Modified metric hex keys ranging from M4 to M10 are now available. It's surprising that these essential tools haven't been developed earlier. For more options, refer to http://objects.reprap.org/wiki/Development:Workshop_Tools. To customize the size for the PRT file, edit it using free Alibre Design express or a 30-day trial of the full version (e.g., to export imperial measurements). The "SIZE" parameter controls this. Although M4 may be pushing it for a 3D printer, larger sizes should still serve their purpose for light to medium applications.
With this file you will be able to print parametric Hex keys with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on parametric Hex keys.
