This is a simple old skool Moxon vise kit for metric M16 threaded rods and nuts.

I printed the parts with the following Cura settings on my Ender 3:

• Layer height: 0.2
• Shell: Wall line count: 4 (important!, these parts need to be sturdy)
• Infill density: 65%
• Build plate adhesion: Brim
• Supports: YES
• Material: PLA
• When printing the washers you don't need a brim and you should set the infill to 100%

You need:

• Two M16 metric threaded rods. Approx 20-30 cm long.
• Six M16 metric nuts
• Two identical wooden blocks (one front and one backing block) for you vise. Preferably some kind of hardwood.

Instructions:

• Glue one M16 nut to to each of the Vise Handles. I prefer epoxy glue for this task.
• Drill two 16mm holes (left and right) through both blocks while perfectly aligned. Approx 30 mm from each side perfectly centered.
• Enlarge the holes on the front block in the horisontal direction, you are gonna need the wiggle room. Do not enlarge it in the vertical direction.
• Insert one M16 rod into each hole of the back block
• Insert a M16 nut in to each of the fixtures and screw them on the M16 rods on the backside of the backing block
• Fasten the fixtures with four screws to the backside of the back block. Do nut use tapered screws since you will crack the plastic.
• Fasten one nut and one washer to each of the rods against the fixture and tighten them carefully, do not overdo this since its plastic after all.
• Fasten the backing block to your bench using your prefered method.
• Insert the front block through the two fixed M16 rods
• Screw one handle and one washer to each of the M16 rods
• Screw one end cap to each of the M16 rods.
• Done
