This bed leveling knob is a beefy, comfortable way to self level your bed. This knob is for an M3 screw, so double check your screw size before printing as this may need adjusting. Also check to make sure the knob is small enough for your printer. If this knob does not work for you, but you like the design, feel free to let me know and I will gladly adjust the dimensions for you. I'm mainly sharing for the design of the knob, not the dimensions or thread size.
