Sapphire Pro Dual_Z Mod

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.

Print Settings:

All parts must have enough stiffness and strenght so I printed them with ABS.
