These are glue together. They fit pretty tight on draft settings. You may easily fine tune that for a better fit. All protrusions are tapered to leave a small pocket for glue. I used super glue and was not concerned with post-processing appearances. They are flimsy, but work quite well. Remix as needed for your cabinet depth.
The print files are setup for the MK3S+ bed size. You simply print in order, and by the quantity named in the gcode (e.g. 2_3x is the second file and gets printed three times). this yields three racks total, you can remix as needed.
The author marked this model as their own original creation.
