Sliding cube/flexi cube/fidget cube 3-sizes

I saw other similar models but none of them slid fully in both directions because there had to be a piece in the middle to hold it together so in my design, I mad the pieces move with it so it can move fully in both directions!! Boost Meboosting me helps me know that you like the model and you want me to create more like it and also helps me create it!! You have to break in the joints in order for it to move so just push the pieces in opposite directions and it will become loose and easy to play with.
