here are some pics of the new bins, i think these are my finalists.
anyway, the pics

1) 2 of the new bins, they have almost an identical footprint as the others except, they hold more than double the nutes.
2) covers, as you can see, almost the same size
3) another angle with the covers and a coke bottle for perspective
4) 1 done, 3 more to go
5) my neighbors kid pissing on the fence
