Tronxy XY-2 Bed knobs

The original bed knobs are too small and don't lock in place very well. These are CR-10 scaled down to clear the sides with a hex for the nut.
I always put a metal washer between the bed and knob and put a small drop of hot glue to serve as a makeshift "lock nut". Keeps the knobs from spinning freely.
