We do make them ourselves. (It's "we" plural because another guy does the CAD work.) Depending on pads you would prefer, we could figure out how to make them. I chose the HyperX pads because another M560 owner glued up HyperX pads on his M560s and reported no loss in fidelity, and also turned the M560 into a great closed can for gaming. He concluded that the M560 planar speakers needed to remain close to the ear. The HyperX pads are fairly thin and accomplish that, but remain comfortable. I agree with him. I tried other cushy fatter pads with my old plates and they ruined the sound.
We already do support fellow headfiers with some 3-D printing. The best one we've done so far is a collaboration on a fix for the M300 and iSine earhooks. Those flimsy earhooks break easily. It was a point of frustration for me as well as other owners. The earhook is a design flaw on an otherwise great planar earphone. I did some prototyping with a couple fellow owners and we came up with a good mod solution. Now, we each buy ear hooks from amazon/aliexpress/ebay and I print and mail the horseshoe clips that fit into the ear hook and mount onto the M300s and iSines. It's a simple solution and it minimizes shipping cost. About two dozen of us are using the combo with good results in both comfort and sturdiness.
I suppose we could do something similar with these plates for the M560s. We would each buy our own pads off amazon/aliexpress/ebay, and then I would supply the plates. You'd probably need to buy your own magnets too, again to minimize overall shipping cost. The guy who does the CAD work for me does not permit me to share his CAD files, so that option is off the table. I asked previously - he said no. As a first step, I probably should buy a set of Shure 1540 pads since they are a highly regarded pad option for many headfiers. I would then verify that they work in the plates, and if not, modify the CAD file for the Shure pads. That would give us two pad options.
