Constructables - Modular mechanical building system

A simple, durable, and easy-to-print construction system designed for creativity, prototyping, and learning.

This project features oversized threaded bolts, nuts, beams, plates, and brackets that can be assembled without tools. Every component is designed to be compatible with the rest of the system, allowing you to build anything from simple structures to complex mechanical concepts.

Features

• Large, easy-to-handle threaded fasteners
• Fully modular components
• Strong printed threads with smooth engagement
• Optimized for reliable FDM printing
• No supports required for most parts
• Expandable with future components

Included Parts

• Bolts
• Nuts
• Beams
• Base plates
• 90° build node bracket

More components will be added over time.

Printing Recommendations

• 0.4 mm nozzle
• PLA recommended for general use
• PETG, ASA, or engineering materials work well for increased durability
• Print with the supplied 3MF profiles for the best results

Compatibility

All parts in this collection are designed to work together. Future releases will remain compatible whenever possible, allowing you to expand your existing collection instead of replacing it.
