The file 'Beginning Addition And Subtraction Manipulatives 3D Printer Model' is (stl) file type, size is 147.8KB.
This is a set of math manipulatives I created for my daughter. They are commonly used in special education programs. (Popular in the UK, I believe.)
For best results, print each number out in a different color (See example.)
There are many commercial and freely available activities that can be used with this type of manipulative. Examples include:

Good for use as practice 3D printing objects the parts do not require any structural support.
(The base is 5x5 since that is the maximum size for my printer...)
**5x5 base now has pegs slightly smaller to allow a bit more "give" to placement of the manipulatives.
