printMATE 3D z-axis nut holder

The z-axis nuts of the printmate are unfortunately only fixed by the weight of the y-axis bar, which holds the Extruder. To fix this problem I designed a "clip" to hold the nut properly in place. This "clip" has a tight fit, so it does not need to be glued or bolted down.
And for all those that also have a problem with the filament spool holder of the printmate, this is my solution:
