The working distance of this design is movable by releasing the stuck latching on the back side of the lever, which is pushing by a spring. Pull the latch and move lever up and down to adjust the working distance. The design of the gear rail on the column is a module 1.2 mm one. It has around 4mm (actually, 3.77mm) pitch. It's not that much in detailed movement, but it stronger and easier printing by must of the 3DP. After defined the working distance, you can adjust the focus on your USB microscope.

The cable hook on the top of the column can hold the cable well.
