This is a stackable storage system running roughly 210x210x85 tall, you can print multiple shelves and stack them vertically without glue due to an integrated interlock system. I printed mine at 0.8mm layer height on a 1mm nozzle, the drawer took 3 hours and the shelf took 4. I would recommend a smaller nozzle due to the thin gaps and walls on the interlocking system, your results may vary. This model was created by myself in Fusion360.
Edit: Screenshots are of V1, V2 STL has been uploaded and increased height by 4mm as well as removed unintended gaps in the base layer
