This is a stand I designed for holding the cheap-o but handy diamond grit file set I bought from harbor freight. I would recommend printing with the "x" side on the build plate, supports are optional but helpful.

To avoid any tippy-ness, I added some small clamps that fit around the base, allowing you to screw them into your worktable. I would recommend printing these with a very high infill percentage. especially if you plan on using a screw bigger than M5.
