First things first, amazing job as always and : I'm very happy to hear you this happy.
Secondly, please forgive the slight highjack of your thread, Mara.
Thirdly, for all those "foam peasants" like myself : while this works perfectly on the type of suit material Mara used, magnets this strong will cause your gun to make impressions into your foam suit (trust me on this - i learned this the hard way)
They will at LEAST botch up your paintjob, in worst case they will damage the foam surface of your armor if that armor is foam-based.
Using weaker magnets is no good : I tried the combination of 2x18kg magnets on my foam suit, and it was not able to keep the gun (the Boomco) secure, although it must be said, the BoomCo with the led mod I did does weigh more than those printed M6G you're seeing there.
Also, I'll most certainly redo them in a future version to include a much stronger peg&hole assembly system, but at that time, I was till having issues making that work in a good way.
Anyway :
I solved this "auto damage" issue on my foam armor by using a tranparant piece of plastic as a "docking surface" where the gun would attach (at that time, I used a Boomco M6G, not them fancy nice big ones Mara's using right here). Or you could make a metal insert in your foam suit and painting that into the same color scheme as the armor itself, but that would still leave you with the risk the (overly)strong magnets as there would be little to nothing between the magnets to impede the magnets total bonding strength) would excert such a high strenght on the construction the metal insert could tear out of the foam parts.
