bearingless x&z-axis prusa i3 (non-wobble fix version)

my original design included a z-axis wobble fix but no everyone wants the or needs the wobble-fix so this version dispenses with it and instead has the z-axis lead screw brass bolted directly to the printed part much as most stock setups are.

*the parts have holes for both brass with 3x bolt points and 4x bolt points

*I include a second design for the motor end of the x-axis so the motor can be used facing backwards or forwards depending on the users setup
