Abstract
This OSAT is appropriate for any locale that has access to a 3-D printer and needs additional learning materials for their curriculum. This is appropriate both for and as a game to teach young children between the ages of 4-9 how to follow rules, how to recognize and apply knowledge of numbers, and how to critically think.
Bill of Materials
Each domino uses 1 gram of PLA 1.75mm filament. For a full set of 28, that is 28 grams of filament. Pricing filament at $23 per kilogram, that brings the cost for a full set out to 64 cents USD.
Comparable sets of dominoes off of Amazon cost $15, creating a difference and savings of approximately $14.36.
Tools needed for fabrication of the OSAT
No special tools are needed for the fabrication of this OSAT besides 1.75mm PLA filament and a 3D printer similar to a "Jellybox", or any RepRap printer.
Skills and Knowledge Necessary to Make the OSAT
Interested in making this OSAT? You only need to know how to use a basic 3D printer, retrieving the design off of the World Wide Web and getting it to your printer. There are no supports needed, no rafts used. This design is 100% ready to go, easy to print.
