This is a 3D printed modular mechanical construction system designed for building structures, mechanisms, linkages, and creative engineering projects.
All parts use a standardized pin-and-hole connection layout, allowing them to be mixed, matched, and expanded into larger assemblies.

The goal of this system is to provide a flexible, reusable, and customizable building platform.
You can print only the parts you need, modify them, or create your own compatible pieces.

Features:

• Modular building units with universal spacing
• Works for gears, joints, arms, frames, and motion systems
• Easy to print, no supports required (unless noted)
• Perfect for STEM learning, prototyping, and creative building

Feel free to remix, improve, and share your builds.
More parts and motion modules will be added soon!
