thingiverse

To keep your bed level and prevent screws from shifting inside their holes, you can add a spacer or washer above the thumbwheel. This simple fix makes the entire bed more stable. You can also place it under the springs for added support. With this adjustment in place, your printer will be less prone to movement and layer shifts, both horizontally and vertically. Each component usually takes under a minute to print, making this a quick and easy solution to implement.
