Designed model to learn thread design and to make a support brace for my new GPU. Simply thread the nut onto the screw and and then screw into main body. Adjust to height needed (61 -93mm) and tighten down nut to secure. Model has a pocket for a 15mm x 1.75mm magnet in the bottom if desired, just add a pause to insert magnet. I printed with PLA using 3 walls and 15% infill.
