The little Tetris pieces are great fidget toys along with being a neat desk decoration and fidget toy. They are very capable of stacking on each other.
The models are scaled so that one cube (being one of the 4 cubes that make up each shape) measures 10x10x10mm for you reference scale. Obviously, feel free to scale these however you see fit.
Thank you for checking out my models. Please like and download, it really helps me out!
