Bed level knob for the Anet A6 or A8. Tried to make it more easy to adjust with my big fingers. This is also useful when having a glass bed and not needing to access the screws under the glass.
Observe that you need to drill and remove the threads in the underlying H formed frame for this to work, and this is not reversible.
Note that in the pictures the linear bearings is upgraded with this 3d-printed bearing: https://www.thingiverse.com/thing:2846316
Provided is also a fusion 360 CAD file if you need to make adjustment.

Assembly
Before you disassemble the bed check that a M3-nut fits snugly inside the knob. It should stay in place by itself. Otherwise slightly modify the hex hole dimension in Fusion 360, and reprint a new knob and test again.
Unmount the bed from the underlying H frame. Drill with a 3 mm drill bit and remove the threads from the holes (se pictures). Optionally use a sink drill to remove any burrs.Fasten the bed screws in the holes on the heated bed with a M3 nut (spare parts from the printer kit). Be careful so you don't damage or short circuit the underlying copper traces. See picture.
Put the heated bed back with the original springs. I have replaced the springs with a tiny piece of silicone tube to be able lower it a bit more for a glass bed, se pictures above.
Insert the knob with the nut inside on each bed screw and adjust the bed level.
