Z Bed support for CoreXY type printers
thingiverse
I built a CoreXY printer using http://www.thingiverse.com/thing:1752766 as a guide. One of the things I changed was the Z mounting piece. I changed it to use a captured nut design. The nut is a tight fit into the part. I have provided the source file incase you want to change it a little.
