Yes, after really having to force a couple of the magnets in I decided on going for 3.5mm. I was really worried that I would end up snapping something off either pressure I was having to use. I was probably compressing the tiny amount of air to about 50 psi 😂.

Not pretty but they are in. To be honest there is more superglue on my fingers than is on the bases.

And why am I doing this? So I can put them on an old saw to spray them. Lol. Honestly I sometimes wonder about myself.
