At my office, we use acrylic shields to divide our cubicles. The shields are held in place with laser-cut adapters. The top of the adapters (12mm x 12mm) sticks up, creating a perfect mount point. Features include “Headphones” label, recessed area for headphones to be held in place, and the supportive grain structure of the print easily holds headphones with minimal bending. I've also created this design with minimal mass to make it cheap and fast to print out. The design fits perfectly (as pictured) with a friction fit that causes no scraping or deformation of the cubicle adapter or shield. I recommend using a glue stick for this print, since the small part on the plate created by the recessed area tends to pop off when I don't use it.
