Sukh, how are you dealing with the problems of the MFC 's having different size mounting nuts on the switches. I got into trouble with the Gigwrx lables not fitting my MFC. I had your labels to start with and they fit fine just wore them out, the Gigwrx that I bought next did not fit. Now looking at your new ones and worried.
Hey mate,
I actually became aware of this anomaly in nut-sizes with the MFCs a while ago and, when I launched KickTags V2, I resized the switch cutout in the magnets then to accommodate. They will either fit snugly or, going on experience with others since I resized the cutout, you'll have the teeniest of wiggle room.
As I've observed others have found over the past year or so, however, it's a simple and cheap job to replace those nuts with easily obtainable smaller alternatives from any hardware store if you feel the need.
