Part of the new Z stage I designed was the capture nut. This method of attaching two 2D pieces to make a 3D assembly relies on a nut being captured and not turning. This is accomplished by keeping the slot cut out for the nut too small. When my parts came out of the laser the slot was larger than expected. I found a solution to this by going to the hardware store (OSH in NorCal) and buying a new nut. The new nut needed the same threads 5/16" but a larger outer diameter. They carry this at the hardware store and it's called "Heavy Nut".
My new novel Z axis is not done yet, and will need another set of captured nut assemblies. I will reduce the tolerances so a standard nut will work.
