Door Knob Child Safety Cover
thingiverse
Door handle safety cover to keep kids out of your printer room. Print with the small opening down and no supports. Included is also my gcode for the Tevo Tarantula printed at .12 layer height. You will need to print two per door. Be advised I haven't tested this yet and it is designed for the door handles I got from Home Depot so it might not work for you.
