There was no dual z mod for my SP-3 printer so I've designed my own. It's not complicated and works very well.

I've designed dual Z mod for my TwoTrees Sapphire Pro. This mod helps a lot with bed shaking while fast printing and printing with high accelerations, it provides better stability for heatbed. You can also use dual z leveling with this addon.
I printed some calibration cube's with 7k acceleration to compare printer with and without the mod.
Parts:
3D Print:
- 4x - Profile_Mount_Bracket
- 1x - Stepper_motor_mount
- 1x - Main_Z_Plate
- 1x - Bed_Plate_Drill_Guide (To drill 5mm holes in printer's bed plate)
To buy:
- x12 - 3x14mm Screw (to mount linear bearings and lead screw nut)
- x12 - 3mm Nut
- 2x - Linear Bearing LMK8UU

You can also use this mod only with lead screw, it will still work pretty well.
