This low-poly ear can be screwed to a wall with no visible screw. The ear part clicks onto the base that is itself screw to the wall.
Use it as a decoration or suspend whatever you need to suspend to it.
About the printing. I've use PLA and bronze composite PLA (shown in my photos here) with success.
I have reduced the need for support to the minimum, still prints better with some supports.
Everything is included in the .3mf files included here. (support painting, infill modifier for the base, variable layer height, etc.)
The author marked this model as their own original creation.
