Modular Stick-Based Shelf System

This system consists of sticks, connectors, and plates that interlock to form customizable structures.

You can assemble it into a shelf, as shown in the images. The number of horizontal sections and vertical levels is fully adjustable.

The key components are:

• stick_Xmm.stl – A stick such that connectors get spaced X mm apart. • connector_Y_sides.stl – A connector that accommodates Y sticks. • plate1,2,3.stl – A round plate that serves as the shelf base. It snaps into the stick system. plate_1.stl includes a holder (e.g., for a filament color label, 1cm thick, see pictures, not included). For symmetry, consider mirroring for the left/right sides.

In the images, you can see how the green connectors work with the white sticks. The top of the shelf uses 3 and 4-sided connectors, while the lower levels use 4 and 5-sided connectors.

My shelf has compartments measuring 23cm x 24cm x 10cm, which perfectly fits standard filament cardboard boxes. You can customize the size by printing longer or shorter sticks to match your requirements.

To strengthen the structure, glue the sticks into the connectors. The plates don't require glue, as they securely fit into place based on their shape.
