Just a fun little exercise in making "floating" mounted objects. The idea is to use a ~4 mm diameter screw (with a < 8 mm head diameter) to mount the "mount" parts to the wall, and simply slide the legs onto the mounts to hide the mounting hardware. Tolerance is about 0.3 mm between mounts and legs.

Notes:
Should not require supports, but may have overhang artifacts. I successfully printed all four pieces without supports but did have a tiny bit of overhand warping. Perhaps support/tree support may give better results. I also suggest using a small nozzle (0.2 mm) if possible for best results.
