Please Close Door Sign

cults3d

My daughter and her second grade teacher came up with this idea when the students were having trouble remembering to close the classroom doors. Fortunately the doors are magnetic, so that makes for easy mounting. Since the signs have been posted, my daughter and her teacher report that the doors have been shut consistently! It's great when a 3D print actually works ;-). The back has indentations for 20 mm round, 2mm thick magnets. I printed with dual extrusion. However, with a pause after the bottom part finishes, this could be done with single extrusion.
