I like the design with the free area below the phone to plug the cable. My idea was to adjust the width of other phone sizes.

You'll find 2 sizes of nuts. The original M10 doesn't fits with my printer without any reworks (maybe some parameters aren't correct or I'm stupid for it). That's the reason of the M11 and this works perfectly.
