Z-Mounts with Increased Y-Gap for Box-Frame Prusa i3

For a standard Prusa i3, the gap behind Z-axis is very tight, so that in my case the rear of the X-carriage collides with the frame as I try to move it out further than the main cut-out - limiting this way my maximum possible printing volume. The same also happens if one tries to use an extruder motor which is longer than 43mm.




While this problem is easy to correct for a single sheet frame (just "lift" the corners by putting some "spacer" between the Z-mounts and the frame)
