Therefore, the top hat for anti-wobble should not have a fixed lead screw position. So, I have created an Adjustable Anti Z Wobble Hat.  # BOM (Build of Material) - M3 * 20mm x 2 - M3 Nuts x 2 - M3 Washer x 2 - 608ZZ Miniature Ball Bearings x 1 [AliExpress](https://s.click.aliexpress.com/e/_AeigFM) # How to adjust the lead screw and lead nut 1. Attach the Adjustable Anti Z Wobble Hat to the top of the Z-axis frame. Do not tighten the screw, but leave the bearing position adjustable.  2. Loosen the four screws that secure the lead nut. 3. Measure the length of the lead screw and the Z-axis frame together with a caliper at the bottom of the leadscrew, around the flexible coupler.  4. Measure the length of the lead screw and the Z-axis frame together with a caliper at the top of the lead screw, around the Adjustable Anti Z Wobble Hat, as close to the same length as the bottom as the lead nut can move. **Be careful not to bend the leadscrew** 5. Tighten the screw on the Adjustable Anti Z Wobble Hat to lock the bearing in position. 6. Tighten the four screws that secure the lead nut.
