Customisable cable rail mount for MPCNC build

The cable rail mount is attached to the top edge of the stepper motors of the upper axis of the MPCNC build and serves the purpose of supporting the cables coming from the Z axis, such as stepper cable or spindle cable. As is, it supports an aluminum rail of ca 20 mm width, but can easily be adjusted to your needs. You'll need two of these, one as is, and another one mirrored for the other end. I didn't bother mirroring in Openscad, as this is easily done in Cura. The rail is attached via M3 screws and corresponding nuts. You'll also need some longer M3 screws to replace the ones holding the steppers. I secure the cables to the rail via cable ties.
