Anycubic i3 Mega (S) Bed Leveling Knob and Lock

<b>IMPORTANT</b>: if using pegs with the original knobs, you'll need to set Horizontal Expansion to -0.3mm due to the hacky way it was designed. You can reduce it if your printer is more accurate than mine. Locks your bed leveling knobs in place so vibrations or overzealous print removal doesn't ruin the level. I started with the peg system to use the original knobs but found it much easier just to put pegs on the knobs themselves. The "Back Right" versions are because I have a bed cable guide installed (modified because the gap was too thing for my Mega S, original is in the "remixed from" list and modified version is in files), and the normal versions didn't fit. They might not be necessary for everyone. You may also need this to keep the bed cable out of the way: https://www.thingiverse.com/thing:3363489 Update: added slim version of the regular lock.
