AM8 MKS bracket - dual mosfet and Z-splitter

Found the original design to miss the possibility to have a PCB with a Z splitter mounted, so mounting holes were added for this.

A more "protective" bottom was created in order to reduce the risk of creating short circuits on the PCB's.

Also, I added printed spacers for the PCB's (which easily can be removed if requested). The MKS board is lifted pretty much - but that is in order to ensure clearance of the USB cable over the screw-terminals of the lower MosFET module.

And to finish th
