Math manipulative block
thingiverse
Math manipulative blocks for homeschooling or whatever, in the style of the Math-U-See manipulatives. These act as a physically movable visual aide for a young student to learn the basics of arithmetic. A full set is 10 of each block. The STLs uploaded here have a pretty tight tolerance to allow the blocks to press together solidly. If your printer has different tolerances than mine or you just want looser blocks that are easier for your kid to stack, open the SCAD file in OpenScad or the Customizer and increase the extra_negative_space parameter.
With this file you will be able to print Math manipulative block with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Math manipulative block.
