This model set allows you to easily build lightweight, modular 2D frame structures using 3D-printed parts.
The main element is a 40 mm-high C-beam featuring built-in dowel connectors on both ends, allowing you to join multiple sections precisely and securely without the need for screws or glue.

A 90-degree corner connector is also included, making it possible to create rectangular or custom frame layouts.

This modular system is ideal for building:

• display and mounting frames,
• lightweight prototypes or mock-ups,
• organizers, stands, or structural panels.

In addition to dowel connectors, each element can be tightened together with M4 screw, for firm and solid connection.

The model is parametric, so you can easily adjust the length of the straight element to fit your specific needs. Length of a beam can be adjusted from 50 mm (min) up to scale of your 3D printer (200 mm beam = 230 mm part due to length of connectors)

Tip: add a negative part (cylinder) in Bambu Studio, to get mounting hole wherever you need it.
