Yet another bed levelling jig.
This one has magnets to stick to the rails...
...and a setscrew to tighten the dial gauge.
Designed for BIBO2 touch, but works well with any printer having 8mm rail rods, 70mm appart (65-75 is ok, though)
TIP: Best accuracy is achieved when bed is heated to print temperature first
M3 x 30mm screw
M3 nuts (x2)
10mm diam neodymium magnets (x2)
Dial gauge with 8mm rod (+/- 20€ on Amazon)
Print on the side (like on the .stl)
Preferably use rigid filament, like PLA. Even if the bed is heated, the jig doesn't stay long enough for the PLA to soften
Inspired by Latigerlilly thing, I redesigned from scratch including set screw and magnet holes on the top (they don't need to be glued)
