This is just a simple headphone hanger for a relatively standard thickness desk (mine was a desk top surface from Ikea, 34.5mm thick). It doesn't require any hardware to hang, and takes up very little desk space. Also, this is extremely easy to print! Please see the printing notes below. I will probably make more modifications over time for looks and stability, but the very first print worked pretty well for me. [Print Settings] Printer: Monoprice Maker Select Plus Rafts: Doesn't Matter Supports: No Resolution: 0.2 Infill: 20% (or more) Notes: I highly suggest printing this part on either of it's side surfaces/faces. It will improve the hanging strength and remove any need for supports. How I Designed This: Fusion360
