These 3D-printable Snap Cubes are compatible with other 2 x 2cm commercial snap cubs/number cubes used in classrooms for maths, counting, and creative play. They snap together with a firm but satisfying click and can be pulled apart easily, making them perfect for little hands!
 

I’ve created 3 different variants with the classic 1-male snapping ring, and added a 2-male and a 3-male design to allow strength and new designs not possible with the original 1-male commercial designs.

I've also added a Base Plate which I've not found commercially. 

(Please note - the photo with the little house and tree had a mix of commercial and these own 3D printed cubes, to show compatibility)
