The Zero G documentation will give you a start building your project, learning all about 3D printing and more!

Getting started

On this website you’ll find all sorts of information, ABS Printing Tips, Print Settings, Design Guidelines, Mainsail Theme, Manuals and more!

Currently we’re working on instructions for two of our projects. Our projects are Mercury One.1 and Hydra.

The documentation is still a work in progress so keep in mind it’s not complete.

Mercury One.1 Hydra

Step files!

The step files for Hydra and Mercury One.1 are now available.

Find them in the menu: Manual → Mercury One.1 OR Hydra → 3. Files. There is a section called “Step files”.
