Just a little flag type marker to identify potentially hidden things in the grass/yard/garden like hidden rocks or objects while mowing. It also is a thinner profile so it isn't caught by winds and such so it shouldn't be pulled out by the elements.
I printed in PETG with 3 perimeters, 0.4 layer height with an 0.6 nozzle.
The author marked this model as their own original creation.
