In our current kitchen, our cutting boards sit on the countertop. And they eventually slide, which was bothering me hard enough so that I had the time to use some 15 minutes to design this organizer in Fusion and let it print for some 7 hours. Problem solved!

Printed it in R3D PETG in white using my Snapmaker U1 and its "0.20mm strength" profile, which translates to 6 walls, 5 top layers, 3 bottom layers, 25% infill (grid), no supports and no brim.

Enjoy this print.
