The ACME z-axis screw can support wider print range than possible with the stock vertical rods. Adding these 20mm by 8mm shims will lift the handle enough that you can raise the XGantry so that the screw top is just about level with the ACME nut. On my v2 TwoUp with heated bed, it extends the z-axis range from 100mm to 120mm.
Note that I route my wires between the gantry and the handle. If you route the wires above the handle, you only need a 15mm shim.
Model in FreeCAD.
