Lee Hardness Tester Microscope Stand

thingiverse

The Lee hardness tester is a great tool for advanced bullet casters (or anyone else who wants to measure the Brinell hardness (BHN) of their lead alloy for any reason). The only problem is that the 20x microscope supplied to precisely read and measure the diameter of the divot made by the die is basically impossible to use freehand. This stand prints quickly and easily without supports, and holds the microscope in the hole via friction. You want it to hold tightly enough that the microscope doesn't slide up and down under its own weight, but loosely enough that you can easily move it up and down to achieve proper focus. The file as-is was just right on my printer, but if you find you need it tighter or looser, you can probably just print the whole thing at 99% or 101% scale on your slicer. None of the other parts of the design will be adversely affected by that small of a change in scale.
