Mill Vise Speed Handle - 12mm Size

prusaprinters

Update June 25, 2022 : The person I originally made this for dropped the handle onto the shop floor, and a bit of the crank piece chipped off. To address this problem, I redesigned the crank piece to make the walls a bit thicker. I also tried printing it in flex as another alternative. Files for this have been added.This speed handle was made for small vise on the bench-top mill of a friend. Of course different vises have different sizes and shapes for attaching a vise handle, so this may or may not work for your vise.This speed handle is intended to be used to make it easier to initially position work in the vise as it makes it easier to tighten or loosen the vise as necessary; after that the metal handle can be used for final tightening of the vise if necessary (though I have found that the speed handle alone works in most cases).As noted, this is a remix of a similar speed handle I made for my own vise. This remix has a short extension and a rotating handle. The handle fitting for the vise is hexagonal - 12mm across the flats and 15mm long. AssemblyThis print requires the addition of a 1/4"-20x1.5" round head screw (or use a metric equivalent M6x1.0 screw). Tap the hole in the handle for the screw you are using, and screw the crank piece to the handle. Print instructionsPrint in PETG using the 3mf file or gcode files provided; otherwise:2 perimeters15% rectilinear infillmodifier around hex socket : 4 perimeters, 80% rectilinear infillmodifier around screw hole : 4 perimeters, 25% rectilinear infillNote the use of modifiers to reinforce the print around the hex socket and the screw hole.CADThe OnShape 3D CAD file for this :https://cad.onshape.com/documents/486cc47efe41d78409dec139/w/a77fb9198589af7459093575/e/91bc280a2ff6e7ddfcc99424
