https://flic.kr/p/aaRRx8 | Plano Box Holder | My project for today. About 4 foot tall (49 1/2 inches), currently holds 17 Plano 3700-series boxes. Once I fill out the rest of the brackets, it can hold 24. This should really help clean up my LEGO workspace! Built from pine 1x6. The spacing on the brackets is tight enough that I could have built this out of 1x3, but I'd rather support the boxes from their centers. Only took a couple hours to put together... I'm pretty happy with the result.
