Project Core 3D Symbols
Setup & instructions
The Project Core 3D symbols are a set of 3D printable three-dimensional (3D) symbols that represent words in the Universal Core vocabulary. The Universal Core vocabulary is ‘a set of 36 highly useful single words that can be used alone or in combination to communicate for a range of purposes on countless topics with a wide variety of communication partners.’
For the 3D symbols, the individual word is indicated with a unique raised element, the printed word, and the word in Braille. The word category is indicated with the shape, texture, and color of the base.
Project Core also provides the symbols in different formats.
These symbols may be useful to help students with visual impairments and/or significant cognitive impairments communicate. For instructions on how to introduce and use these symbols, refer to the original site: http://www.project-core.com/3d-symbols/
|Word Class||Shape||Edge Texture||Color|
|adverb||circle||bumps (reverse golf ball dimples)||yellow|
|verb||triangle||vertical ridges like a quarter||red|
|noun||trapezoid||horizontal wavy grooves||orange|
|interjection||pentagon||single string of bumps (string of pearls)||black|
Each symbol requires less than $1 of plastic. The cost of materials for the three starter symbols is about $1.50. A full set requires $18 worth of plastic. The total cost to produce these may be increased if the different colors are required. (A 1 kg roll of filament is typically $25-35)
Each symbol is 3D printed. The files can be found at the linked GitHub repository or on the original site.
- 3D printing
Each symbol takes approximately 2 hours to 3D print on its own. A total set may then take up to 73 hours to print.
The symbols are a simple print and do not require support. Refer to the 3D Printing Guide for instructions. Multiple symbols of the same color may be printed at the same time. The red symbols may require two separate print setups to fit all of them.
The 3D Universal Core Vocabulary Symbols were designed by The Center for Literacy and Disability Studies.
The Bill of Materials and the 3D Printing Guide were created by Neil Squire / Makers Making Change.
