Desk support column (G-clamp)

Have you ever found yourself needing to support a shelf, because it can't support itself? Well, that happened to me. I had the shelf plane but no way to support it, so I designed this. It's a column with a stonework pattern on it that also serves as a G-clamp, but if you'd rather just have a decorative column, there's also a version included without the clamp. Please note that I haven't yet tried to print it myself as my printer, just like my shelf (and myself), is badly in need of support.

DeskColumn is the base form, the pillar without the clamp. DeskColumnClamp, rather obviously, has the clamp attachment, and the Screw and Snap files form the screw meant to fit into the G clamp.
DeskColumnDemo is just an assembly of the files to show how it's all meant to fit together, and is likely not print-compatible.

The text reads Nosce Te Ipsum ("Know Thyself" according to my friend who lives in Ancient Rome), and the stonework texture pack comes from https://dwgmodels.com/1145-stone-m
