Stackable Tray System

Overview

A modular, expandable storage system consisting of stackable shelf units and interchangeable trays. Each shelf slides onto the next via an integrated locking rail, allowing the system to grow in every direction without additional hardware. Trays slide into each shelf independently, making it easy to swap, rearrange, or print only the tray types you need. The system is designed with future tray variants in mind (the shelf unit remains unchanged regardless of tray type.)

Currently available tray variants:

•  Classic tray — general-purpose storage
• Resistor tray — compartmentalised storage optimised for electronic resistors

More tray types are planned for future releases.

Parts list

• Shelf unit (one per stacking level)
• Classic tray (optional, general use)
• Resistor tray (optional, electronic resistors)

No hardware, screws, or adhesive required and no support used in the printing process

Tips

• Trays are interchangeable between all shelf units and I will try to keep it that way in future.
• New tray types will be added in future updates. The shelf unit does not need to be reprinted to accommodate them but if you want to use them simultaneously you will have to print one per tray.
