Bed Leveling Knobs For Anycubic i3 Mega

There are many bed leveling knobs or knurled nuts for the Anycubic. Surprise! Now i have one more for thingiverse! :-)

But what i haven´t found on thingiverse solving my problem was this:
Because I was really annoyed that I had to level all the time, because the original knurled nuts didn't hold well, I designed new gears, into which you can press self-locking nuts. Finally the bed level holds!

Try it. I promise, it's really very good...
