Made this a full size version from my original that is also here on Thangs. Minimal supports needed. I block the nut recessed areas, they don't need support but the slicer will want to put them there. I included some pics of the blockers and the supports form Cura. Printed with .2mm layers. Recommend 1.2 mm walls and top, I went with 3mm on the bottom, this gave it a nice rigidity for the belt grooves. Pop in the M3 nuts after printing and secure them in place with a screw before installing on the printer, this will seat them well and let you know if you have an issue. All the holes are in the same locations as the MS metal version, so attachments like CR or BL touch can be added without any issues, as well as fan shrouds. I flipped the hook on the right for the wiring (ender 5 MS plate has this), it made more sense to me the way I have it. You still need the Micro Swiss extruder hardware for this to work, if switching from rollers to linear rails and you already have a MS DD extruder, then this is perfect for you. Pica aren't the best but you get the idea.
