Created based on the models from this project created by u/zruncho, from a suggestion I got by u/computermedic78 for a cheaper alternative to metal rails.
The original z sliders were designed for 1515 extrusions on a Voron v0.1 variant to replace the MGN7H z rails as a cheaper alternative. See https://github.com/zruncho3d/DuelingZero/blob/main/DESIGN.md#z-sliders for more info.
I also have a version for MGN9H rails here: https://www.printables.com/model/317615-printed-zslider-mgn9h-rail-replacement
The more dimensionally accurate your rails dimensions are, the better these will perform. I have a mixture of cheap extrusions and nice ones and it works across all of them, but it's much more rigid with an exact 6mm slot. You may need to tweak them to get a perfect fit, STEP files are included.
There are two versions:
ZSlider_MGN12H_v1.0_IN - Version for 4x m3 Heat Inserts. This matches the original MGN12H block dimensions + the height of the rail we are replacing.
ZSlider_MGN9H_v1.0 - Version for 4x direct m3 screws. This matches the original MGN12H block dimensions + the height of the rail we are replacing.
