Door Flag Magnetic Mount
thingiverse
I took the 3 flag file from https://www.thingiverse.com/thing:2411288 and enlarged the holes to make it easy to use round magnets I have to mount this to a metal door frame for a non-permanent flag solution. If it works well enough, I'll redo the other flag mounts as well.
