Screw Together Gridfinity Negative

I was trying to make larger holes for the magnets that fit every other project in the general landscape since the original ones didn't fit. Oops! I made this model's internal cavity that you can use to make as many weird baseplates as you want. https://www.printables.com/model/300603-gridfinity-screw-together-baseplate
The threaded inserts that I'm using are 4-40, and they seem to work reasonably well. The best thing about the original print is the holes in the back of the plate, since you can masking tape the magnets in place and then glue them from the underside.
