This is my version of a hole plug for the Flashforge Creator Pro. It keeps foriegn objects from dropping into the bottom of the printer and also helps keep the wires orderly. I built it with ABS and 100% fill.
Note: Please check the connector and wires to the build plate heater. While building this, I noticed that my wires and connector were burnt. I replaced the wires and soldered the new ones directly the connector pins.
