This is something I created for my own use when drilling multiple pieces of aluminum in succession.
The normal large steel handle is necessary when milling to hold pieces securely. Light duty is where this 3D Printed handle shines. Made with PETG Fliament and 80% Gyroid infill with printed threads for the locating threaded knob. Check out the awesome knurling…3D Printed also! My new version will pretty much handle anything you can do with your fingers.
Fits any 12mm Hex, most three inch mill vises come with a 12mm hex. Comes with one locating threaded knob.
