Connector Nebulizer
The Connector Nebulizer is a 3D printed connector for air tubes, developed to fix a specific nebulizer equipment problem. It joins sections of nebulizer air tubing to restore functionality where an original connector is broken or unavailable.
The connector is 3D printed using ABS filament.

Field Ready develops manuals to support both the fabrication and safe use of its products. A maker manual provides step-by-step instructions for replicating the design, including materials, tools, and assembly guidance, so that makers in different locations can build the product accurately and consistently. A user manual, where applicable, explains how to properly set up, use, and maintain the product once it is built, helping ensure it performs safely and as intended for the end user. Together, these manuals make the design accessible to both fabricators and the people who ultimately rely on the product.
