I had some issues with binding on spools, and decided I didn't want the spool attached to the control box any more.
So, I designed this overhead spool mount. It's designed to direct bolt on to the upright on the CR-10. Made the M5 counterbores deep enough to catch thread again so you can use the same screws.
I recommend a raft and support at the build plate, should print without any additional support without issue.
