Screw Jack for K40 Laser

thingiverse

Screw jacks for supporting the bed of K40 laser cutters can be built using simple materials. Materials: * 5/16-18 threaded rods (12 inches long) * Brass nuts from Home Depot * 3mm socket head cap screws, approximately 20mm in length * A round metal disk, 1.5 inches in diameter, to prevent the laser cutter from damaging the 3D printed components To assemble the screw jacks, start by cutting the threaded rods to a length that matches the top and bottom parts at their minimum height. Next, use a Dremel tool to create a slot on one end of each rod for a flathead screwdriver. Begin by installing brass nuts into the base component. The nuts should fit snugly but may need to be tapped into place with a hammer. Screw the threaded rods into the base, leaving about an inch and a half of exposed thread at the top. To secure the rod in place, use a screwdriver from the back to prevent it from spinning while heating one end with a lighter. Then, screw on the top component onto the threaded rod. Finally, drill a hole into the side of the top component and install the 3mm socket head cap screws to lock the assembly together.
