The Straw Holder is a lightweight, 3D printed device designed to help individuals with
disabilities who are unable to hold a straw steady while drinking. It fits onto the top of a cup or bottle and holds the straw securely in place, so the user does not need to grip or stabilize the straw themselves, making independent drinking easier and more reliable.
The holder is 3D printed using filament, with certain grades of PETG, PP (polypropylene), and specific types of PLA identified as food-contact compliant material choices suitable for a device that comes into direct contact with a drinking straw and beverage. To use, the holder is placed on top of a cup or bottle, and the straw is then inserted through the holder.
This design was developed for and used by students at Hilton Special School in Suva, Fiji, to support students needing assistance with drinking.

Manuals
[edit | edit source]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.
