Stackable Shoe Rack dual color + printable board

Wanted to utilize multi-material printing so made a dual color version of the rack side panel. For this I decided that best result is achieved if the honeycomb is already in the base model. Also wanted to use lots of PETG so I designed a printable 1 meter long board with voronoi pattern. Full board is available in case you are lucky enough to have big enough printer, along with the board split into 4 parts. I also designed board end parts to lock the printable board in place. The included spacers are for aligning the split board parts. The split board parts are joined together with 2 M6 threaded rods. You'll also need 2 M6 nylock nuts, 2 M6 nuts and 4 M6 washers. The end parts use 4 ~12mm M3 sunk head screws. Since the printed board probably is not strong enough, even with the threaded rods, a middle support part is also available and recommended. I used PETG for side panels and recycled PETG + PET mix for the board. 0.6mm nozzle, 0.24mm layers, 3 perimeters and 30% or so infill.
