Summary
This is a rigid stable Z lead shaft upper holder with a double decker structure. Which holds X, Y and axial loads. Then this reduces axial loads for the Z stepper motor and reduces occurrence of dimensional error by compression of the internal spring of the Z stepper. Therefore the accuracy of the Z movement and printing is improved.
| Stock : Direct axial loads to the Z stepper | This holder : Reduces loads to the Z stepper |

Compatible for Neptune 2 and Neptune 3
I confirmed this working on ELEGOO Neptune 2. The official CAD data indicates the Z lead shaft position of the Neptune 3 is compatible with Neptune 2. Therefore, this may also work on ELEGOO Neptune 3.
BOM
This holds X or Y directions by a 608 ball bearing and holds axial loads by a F8-16 thrust bearing.
| The F8-16 direct on top of lower part | The 608 press fit to lower part from bottom |

 |
note: It is important to use the any metal stopper (pulley or set collar) ON the thrust bearing.
| Part | PCS |
|---|---|
| 608-2RS or 608ZZ ball bearing | 1 |
| F8-16 thrust bearing | 1 |
| Bore 8mm 2GT pulley or any metal set collar | 1 |
| 20mm metal standoff | 2 |
Dual Z Shaft
If you plan to use this onto the dual z shaft, mirror left and right the bottom part.
