After switching to the Klipper Mod from DrAlex, I've had constant issues with bed level drift. I would tune bed screws to get a good level but after a single print the level would drift and become unleveled.

I thought about using thread lock paste but wanted a pure 3D printed solution.  The lock loop onto the bed screw and then clasp to the two mount screw on the under belly of the AD5M bed. 

See the photos on how to install.  You can angle the locks to use them as a wrench to do final fine tuning turns on the bed screws.

Print 4x locks can be mount on any side of the bed screws with the expection of the rear right screw.

Update: I found the friction mounted design go loose over time with the heat transferred from the bed to the bed screws. Redesigned with 8mm round neodymium magnets (1.8mm thick) to provide mounting pressure against the bed.  The bed locks still work as friction mounts locks but I recommend getting magnets.

I can custom design the magnet slots to what you have if you message me.
