Some non-steel jaws for my vise (Irwin 4.5" light-duty). The plate is a little thicker than OEM (to account for eventual plastic deforming), but otherwise is an exact fit.
I don't know if these jaw plates will fit any other vises, so you'll want to take some measurements.
My vise plates were 114mm wide, 14mm high, 5mm thick. The screw holes were ~5.45mm diameter with centers ~22mm from the edges.
2 STL files are included:
- just a single plate
- two plates (oriented to fit on a ToM HBP).
I suggest printing at 50% fill (or higher). As pictured is 60% fill.
If any changes are needed (or you want to customize the plate face), see the openscad file.
