I designed these bed leveling knobs because I want to level my bed accurately. The larger knobs do this job perfectly, but I don’t want to touch these knobs once I have leveled my bed properly. The larger knobs can be touched (and adjusted) accidentally and with these knobs it’s possible to rotate the lever to the center of the bed, hence away from you, so you can’t touch them that easily. I use an adjustable Z-stop so that’s the reason why I don’t want to touch the knobs. I recon this can be useful too if you use a bed leveling sensor.
This is a bit of an experiment so if you experience any issues, please feel free to contact me.
