4 New Leveling Knobs !
Hi there !
I just made a new improvement to my U20 ! This improvement is essential if we want: - The settings are more comfortable! - more precise bed adjustment! - No glue or fixing to install it! In addition, this model is extremely solid! I needed to make this improvement because it is a crucial step before making another new one! I'll tell you about it in another video
The STL file is available in video's description !

If you incorporate a nylock locking nut into the levelling knobs - it's much better and once set, beds almost never go out of level.

yep made these for my ctc i3:

fairly basic.
You just jam/glue the locknut in the middle. As there's no vertical stress on the knob, that works fine.
Think these use nuts for 3mm bolts. But easy to adjust in openscad:
// locking nut wheels
// wheel 20mm height 9mm
$fn=100;
nc=5; // number cutouts
nk=nc; // number knobs
difference(){
cylinder(d=20,h=5);
cylinder(d=6,h=9,$fn=6); // size of locking nut
for (i = [1:nc]) rotate([0,0,(360/nc)*i])translate([0,10,-0.5]) cylinder(d=8,h=10);
} // end diff
rotate([0,0,35]) for (i = [1:nk]) rotate([0,0,(360/nk)*i])translate([0,9,0]) cylinder(d=5,h=5);
