This remix is for a K40 with wheels. I changed the design, so that the threaded bar does not protrude from the bed and cutting area is not wasted.
The bottom holder contains a 8mm nut to hold the threaded rod and is screwed to the bottom with M4 screws. The timing pulley is fastened to the rod and with a ball bearing mounted to the top holder. The belt is tensioned fairly tight with cable ties.
I printed the parts with 25% infill and support.
