Print custom L-brackets and bars so you can build Meccano-style models without buying expensive parts.
Uses teardrop holes that print without supports, saving you time and waste on each piece.
Parametric design lets you tweak sizes to match your project needs.
Open-source library grows over time, so more parts become available as community adds them.

Build your own Meccano toys and structures from scratch. You get a design library that lets you print the exact parts you need, when you need them. No waiting for shipments or paying full retail prices.

The OpenMeccano Lib gives you L-brackets and bars that work with real Meccano systems. The holes use a special teardrop shape, so your prints come out clean without needing support material underneath. That means less post-processing and stronger final pieces.

This library is open-source and made to grow. Start with the core parts and expand as the community adds more designs. You control the size and fit of every piece to match your vision.
