Remixed Z-Axis Stabilization

thingiverse

Even with the anti-backlash leadscrew, the Ender 5 bed tends to drop once powered off, especially with mirror or glass beds. One major cause for this is the z-axis leadscrew's tendency to suffer from axial precession (wobble). This add-on fixes the issue and stabilizes the bed significantly. In the original model, the hole was undersized, with a too-tight tolerance. I didn't have a drill to expand it, but this version of the model doesn't require any expansion. This new model is designed to work with M4 nut screws, though M3 will also work fine. My setup uses M3 * 12 screws with two washers on both sides. I included a copy of T-nut adapters from https://www.thingiverse.com/thing:1609323. Two of these are necessary to fit the part to the 2020 aluminum profile.
