Our Mission
We aim to make open hardware as accessible and collaborative as open-source software. Our mission is to:

  • Encourage sustainability by repurposing common items, such as mason jars.
  • Provide parametric designs for flexibility and customization.
  • Develop a robust open-source ecosystem where contributions are straightforward and impactful.

More Open Projects

SCUTTLE team Nigeria:

For Makers:

  1. Standardized – Compatible with standard mason jars.
  2. Functional – Watertight or airtight with appropriate post-processing.
  3. Efficient – Prints support-free on basic desktop 3D printers.

For Users:

  1. Food-Safe – Use ABS plastic for food-related applications.
  2. Dishwasher-Safe – Durable when produced with ABS materials.

For Designers:

Why OpenJar?

This project aims to transform open-source hardware by focusing on:

  • Parametric models for flexibility.
  • Comprehensive documentation to improve collaboration.
  • Fully digital designs to facilitate widespread contributions.

Our goal is to empower hardware designers to collaborate as seamlessly as software developers.

Adapter Threads
The adapter thread system enables modularity and easy printing without supports. Each adapter consists of two parts: the lid adapter and the thread component.

Spray Bottle Adapter
Uses lid_adapt.stl and thread_spray.stl.
