What about using small washer on the bottom plate instead of magnets

[NDW89]

First off extention is awesome love it. New to Gridfinity so I have been thinking of how I want to design some new drawers I built.
The Pad function amazing, I was adding padding by hand now I don't.

So I am in the delima of magents or not. Leaning more to using them because the drawer on wheels.
So I was looking around and found this guy with a possible solution of just using washer at the bottom of the bins, plus the connector on the bottom, just some triangled connectors. Magents on the bins and just washer glued to the base plate, no need for dual magnets and polarity issues.

Just a though, any way can't say enough that what you did here is pure amazing, love it.

I guess I could use washer just increase the size of holes and reduce depth. Just thinking what if we could in each grid, we could say manipulate the cross holes. 1 and 3 for screws and 2 and 4 for what ever size, like magents or washers, and even with holes or not.
