Z alignment card for Anet A8 & P3Steel

thingiverse

I've been fine-tuning the Z axis for a while now using an old credit card. However, it's just not stiff enough to hold its position. I came up with a straightforward fix that lets me insert this adjuster between the motor screws and the threaded rod holder. Once both pieces are in place, I can manually level the Z axis by disabling the motors step by step.
