This PLA headphone holder is ideal for those with shelves that are 31mm tall (or thick) and have average sized over the ear headphones. Nozzle temp: 220°C, bed temp: 60°C Enjoy. ;)
I ran out of filament mid-print, bummer! Anyway, instead of starting over, I dragged the 3D model down on the slicer the exact amount that was printed (measured with calipers) anyway, there will be sanding, gluing, sanding, and painting in my near future...
