Quick thing I threw together to organize my cutting boards to keep them standing neatly out on the kitchen work surface instead of having to dig into a drawer every time I cook, or just have them laying there on the countertop since that drove me crazy. Or trying to lean them up against the wall and them falling over all the time.

Small standing cutting board rack for plastic cutting boards <6mm (1/4") thick.

Added a 90degree version that orients the cutting boards parallel to the walls they're up against.

Room for 6 since that's what I have.
