This is a stackable holder for sunglasses (or any kind of glasses) that can be mounted to a wall, or simply stacked in place and left freestanding.

Assembly is simple. Print the armature as many times as you like, then slide the top tab into the bottom receiver. The holes should align perfectly for mounting. Use a screw to attach the holder to the wall. The end of the armature has a receiver for a cap. Leave the cap off if you need to slide your screwdriver down through the armature to attach it to the wall.

Once you've got it screwed in, use the cap to finish the appearance. There is also a plug if you want to round off the armature. The plug snaps into the center of the armature. Either way, fold the temples of your sunnies flat, then mount them on the armature just like it was a nose. Adjust the temples of your glasses to stabilize them on the armature.
