Alfawise U30 Pro / Longer LK4 / LK4 Pro Dual Z Axis support plate

I recently upgraded my 3D printer to a direct drive extruder, but with the increased weight on the gantry, I notice a significant amount of drift toward the unsupported side of my printer. In this case, I should also upgrade the printer to dual Z-Axis.

Unfortunately, I am not able to find an existing kit available for purchase or 3D printable mount for the second Z-axis lead screw, so, I just make one for myself and put it on Thingiverse.

The printer I upgraded was an Alfawise U30 Pro / Longer LK4 Pro, this mount should compatible with most Alfawise or Longer 3D printers.

You need to 3D print 2 parts and buy 3 other parts to complete this dual Z-Axis upgrade:

3D printed parts:

1. Lead screw mount (This item)
2. Stepper motor bracket (by KyleRL):

Parts to buy:

1. T8 lead screw, in my case, it's a 350mm 4 start 2mm pitch, it came with nuts and M3 screws

$14.99(2pcs) (You only need 1 lead screw for this upgrade) https://www.amazon.com/gp/product/B07P8P6J5V 2. Coupler 5mm to 8mm

$5.99(4pcs) (You only need 1 coupler for this upgrade) https://www.amazon.com/gp/product/B08LM9DLY8 3. 45mm M5 screws

$7.99 (25 pcs) (You only need 3 pcs for this upgrade) https://www.amazon.com/dp/B088LSS9FT 4. M5 Spacers / standoffs

$12.5 (10 pcs) (You only need 3 pcs with the 45mm M5 screws) https://www.amazon.com/dp/B009YMJDRG

If you buy everything from amazon, it will cost you around $40, this includes more quantity than you need. If you can find somewhere else to buy less quantity, this dual Z-Axis upgrade should only cost $10-$15.
