Gantry Ballast to improve layers

thingiverse

I was having issue with inconsistent layers because of the wave springs in the steppers on the Z axis ( I have dual lead screws) so I designed and printed these parts to add weight to compress them. It works well! WARNING! If you do not have anti-backlash nuts, at the end of the print when the power is cut to the steppers, the entire Z gantry can drop to the be or on top of your print! If you have one lead screw, you can probably get away with one 123 block. You well need to stop the print of the holder at 25mm so the top wire rail will have some where to attach. OR... you can slice off the top in meshmixer. No supports are needed. No brim needed if your bed is level and the first layer is printed well.
