I have modded the heatbed on my MK3S with the nylon lock mod and installed the Prusa Levelling guide plug-in on Octoprint - it's a great addition and I have been able to get my bed very level using these tools.

However, I got tired of adjusting the screws by eyesigt so I made these two little prints - one goes on the hex screwdriver and the other is just held on the buildplate over the screw. Using this made it far easier to use the decimal turns value to get consistent results when adjusting.

Nothing special - I made mine in PETGI had Prusa Orange available but can be done with anything. 0.20 layer height and 0.4 nozzle.
