This is my Astro A40 headset holder that i designed for my IKEA desk. This is designed to clip onto a desk with a 20mm height. This should also work for any headset, as the A40's have a larger than usual headband width.
This was printed on a Rep 2, with a .25 layer height, and a 15%infill, 2 shells, and 230C. Took about 35 minutes to print. If you have any questions, feel free to ask.
