A simple machine vise I made with some leftover aluminium extrusion.

You'll need the same extrusion profile for it to work.

Part you'll need:

• One printed Moving_Jaw.stl
• One printed Jaw.stl
• One printed Fixed_post.stl
• One printed Handle.stl
• At least 270mm 30 "I-type" 60x120mm profile aluminium extrusion. This would give you ~100mm jaw opening. Longer extrusion gives you bigger opening
• 14 x M5x35mm socket head screws (DIN912/ISO4762)
• 4 x M5 nuts for the aluminium extrusion
• 1 x M6X10-28mm countersunk socket head (DIN7991/ISO10642)
• At least 190mm M16 threaded rod (DIN975/ISO whatever), this is for 100mm jaw opening for a bigger opening you'll need a longer one.
• 1 x M16 nut (DIN934/ISO4032)
