Design is using dovetails to lock and/or unlock the self as needed. Currently have a 100mm (3.94inch) deep self with plans to create hooks and other items using the same backplate. The honeycomb cut outs on the bottom of the shelf are 20 mm apart. Using Prusa slicer its very easy to cut down to other sizes. Everything is printed using my Ender3 V2 neo with a .6mm nozzle and .4mm layer height. Attached files from Prusa slicer
