• Trays stack and spin on a threaded bolt base
• Label-ready rims for SKUs and sizes
• Prints cleanly on most FDM machines

Meet the stackable bolt desk organiser. A 3D printed bolt forms the base. A tall threaded shank drives the system. Each tray behaves like a nut. Spin it on. Spin it off. Stack as many layers as your workload needs. The result is a compact tower that keeps screws, nuts, washers and O-rings in clean, separated tiers.

The trays feature smooth chamfers for easy pick up. A shallow profile speeds sorting. Label pockets on the rim let you mark sizes or SKUs for instant scanning.
