3D Printed Cube Connectors

when looking into the possibilities of 3D printers i hit a flaw and that was that 3D printers could not print things in a material that could move like material so i set out to create 3D printed object the could move like material and this is what i came with.
The cube connectors are small squares that can be 3D printed on two parallel sides are made out of cylinders and the other two parallel sides are square rods with clips that clip on two the cylinders. Unfortunate due to my lack of a 3D printer or money i was not able to print them out  but i hope other people can use this idea and elaborate on it.
