Adjustable Z stop for alu bed

When you do the aluminium bed upgrade you need to reposition the Z switch board. Thing designer xxricsxx shows in the video that he used the bed itself to activate the Z switch. Since I use 6mm and 10mm nozzles I wanted more adjustability than just the bed springs. Therefore I designed the bracket that attaches to the Z drive block of the design.
Just add a (long) M3 bolt, a M3 nut in the bracket and a M3 (wing) nut to secure the bolt once set.
