This set can be extended if you want to- I can sell all the parts separately if you have your own design ideas. The only limits to how far this system can go is the space you have.
Thanks for looking and let me know if i can help in any way. Please note this is a non genuine compatible spare part. And the manufacturers names are for reference purposes only. These items are my own design made from pla with a 3d printer, due to being 3D printed you will see layer lines in places as this is the nature of 3d printing.
