This modular pyramid set lets you build 3-, 4-, and 5-sided pyramids using a flexible connector system designed for learning, experimentation, and clean assembly.

The models are based on my customizable connector ecosystem:

• Customizable N-Way Connector – Pyramid Apex
• Customizable 2 & 3-Way Connector – Adjustable Angles
• Customizable Assembly Dowel (6 mm diameter)

Together, they create a simple but powerful STEM building kit for exploring geometry, structures, and modular design.

What’s included

The 3MF file contains:

• 3-sided pyramid
• 4-sided pyramid
• 5-sided pyramid
• test plate (to test the fit between the connector and rod)

Each plate prints one complete set.

Printing setup

The file is prepared for efficient multi-color printing:

• Uses Print Per Object
• Connectors and rods can be printed in different colors in a single job
• No filament waste from purging towers
• Fits on an A1 mini build plate

Notes

• For best fit, tune tolerances based on your printer
• Works well with PLA and other materials (make sure to test fit due to tolerance adjustments)
• Great for STEM education, prototyping, and desk builds

Let me know in the comments which pyramid versions you’d like to see next.
