This device was created for a very specific purpose. My wife works in a special education classroom, for severe and profound disabilities. One of her students is both nonverbal, and has extremely limited dexterity, which has proved a serious challenge, not only for education, but even simple communication with this child. The child is capable of rough manipulation with one hand and a mitten grip, but very little more. There are suitable lever-based communication devices available commercially, but since they are “medical equipment”, they are prohibitively expensive, and difficult to acquire.
So, we designed this! This is a simple, lever-actuated, all-mechanical device that uses an indicator arm inside the box to show a red, yellow, or green colored panel through a window. They have been finding this useful not only in the original intent of yes/maybe/no, but also by placing things on appropriately colored plates, or indicating them with colored tokens so the child can make selections between items.
All parts of this device are designed to print without supports, on any standard 3d printer, using any material you have handy (the ones we have made are in basic PLA). I printed mine on my Prusa XL using multiple tools, but you don't need anything like that fancy! The multi-colored segments on the indicator arm can be done with by filament swaps to print the colors (the swatches are separated in height to make this possible) or they can be painted after printing.
You will also need:
14ea #8 sheet metal screws
1ea ¼-20 x 1.5" hex bolt
1ea ¼-20 x 3.5" hex bolt
2ea ¼-20 nylon locking nut
1ea ¼" washer (optional, but nice)
Philips Screwdriver
There is a PDF of instructions included with pictures to detail the assembly, but the design is intended to be forgiving and user friendly. If you see any improvements you would like, please let me know! This is a work in progress, and I am planning to update it as more people print and use it to give me feedback on things they would like to see.
