Elegoo Neptune 4 Pro (+others?) Bed Screw Lock (no disassembly required)

Apply these to your bed screws after leveling to prevent them from loosening.

1. Insert the big thingy (try not to move the screw).
2. Push the two pins through the holes to keep the big thingy in place (you can skip this, but mine tends to pop off when I test-turn the screw).

Pro tip: If you don’t use black, it’s probably easier to see what you’re doing (too late for me!).

Printing:

• Print upside-down ("teeth" on top)
• Extra fast settings (0.28mm layer) work fine
• No support
• Default infill 15%
• PLA

Tested on my Neptune 4 Pro. It probably works on other models as well.
