This is a headphone stand originally designed to fit the Sennheiser SDW 5061 headphones, while being charged by the magnetic adapter. Although similar chargers exist, this one will cost you much less than the commercial. The panels are cut from 6mm Acrylic, but the thickness can be adjusted through the included .3mf and .f3d files. Assembly uses M3 bolts with a ⌀5.5 mm head.
