Multiboard system by 'Keep Making' has a fun start and is inspiring, but no simple way to just use the bins directly with a "Multigrid" (the existing sytem requires you also lock into a "multiboard" this is a simple tube that turns both sides into a snap fit. think lego, but you can pop the nubs on and off. this feels much simpler (IMO) and fits my needs of simple locked bins in a grid. (I added the peghole screw compatibility to the center)

P.S.: if you're reading this Keep Making, I would love to get rid of all the lock hole variants, or a better explanation for a simpleton like me that just wants smooth bins locked together. also, if you could add slight pitch to the bottom of the holes on the bins so my potato of a printer could more easily print without wasting material on support for the overhangs, that'd be wonderful 🙂. Excited to start iterating!
