Pimax DMAS variable extension

This is an extension for the Pimax DMAS system similar to the one which was available originally. Base and ring will extend the DMAS speaker around 15 mm plus ear cushion height; if one needs more the spacer could be attached. It fits very tightly to the original speakers cover, so TPU instead of PLA might be a good choice for the base in order to avoid any scratches to the original DMAS speaker.A very original looking ear cushion could be found here - the original one seems to be of 75 mm diameter with a inner hole of around 45 mm and a height of 20 to 25 mm.If one is using the 75 mm diameter cushion the ring must be resized.
