These are improved versions of the X and Z mounts by Ryan Matthews found at

They no longer requried drilling any holes.

The Z mount uses an existing mounting bolt.
Just remove one or both of the washers.

The X mount uses a T-nut in the side of the T-Slot plate.

Materials and methods

M3 nuts and bolts
