This wooden box — featuring two pieces each of eleven different color swatches — is a Montessori Color Box, which is a learning tool for schoolkids.

You're looking at a universal handle for a rongeur, which is a surgical instrument used for nasal surgeries. Part of this thing snaps into the handle, while the arm on the side locks it into place.

After a lot of research, a commenter said these things are where the downspouts — or drain spouts — exit from the roof or the interior of the building.

It turns out these are attached to zippers to prevent bed bugs or other pests from getting inside the bedding, as the zippers are where these critters typically get in.
