Frustrated with egg crate and plugs that don't really fit neatly on it without spaces and/or overlapping, I overlaid small plug and large plug layouts on top of each other. The result is a rack capable of holding one or the other or both together while maintaining very uniform spacing.
48 small plugs
24 large plugs
Large holes will work with thicker 3/8" plug stems such as Ocean Wonders.
