I just finished my Primo Build so here’s my old Burly parts if anyone wants them. You just pay for shipping.
THE GOOD: Worked well when in service (see pic #4) Also, free!
THE BAD: The Z_Lower part is cracked at the pinch bolts, should probably be re-printed, but still keeps the coupler against the bearing.
THE UGLY: Due to size restrictions on my original printer, I had to split the XYZ plates. They are rigid enough for use once the core was assembled. When you add the lead-screw nut to the top it’s solid. Also the bottom XYZ plate didn’t finish printing due to a power outage, but (see THE GOOD) 
Here are some pics:
You also get the DW660 mount and the 2 conduit end-caps that didn’t break when I broke it down.
