Small M3 Knurled Bed Leveling Knobs

For my recent build of The 100, I wanted some small leveling knobs, so I made these with a knurled pattern for grip and aesthetics. They have a diameter of 25mm and have a hole for a 4.6mm outer diameter M3 threaded insert. These will work on any printer with M3 leveling screws, you can even swap out M4 screws with M3 like I did with my Ender 3 bed.
