I have designed some additional grills for m1060. I really like the hexa hole one, but it makes the headphone even more bulkier. So i have made my own version. Its a bit slimmer. Smaller holes and rounded edges. https://www.thingiverse.com/thing:3152726 The ther one is simpler. https://www.thingiverse.com/thing:3152668 My bigger plan is to design a (hifiman susvara/LCD X style) headband from TPU. What do you think how wide should be on the widest point? I think 65mm is enough.
