To sum it up.

Just find a piece of tubing that's big enough and hard enough plastic to connect the bin cages?

I've put a list of possible tubing options down below which are a most likely go to/find but if I can't get my hands on anything in my area I will just look for anything that can fit in the criteria.

- PVC tubing (since it seems these can be transparent too, also with caps if I ever want to block off the bin cage then this seems like a good go to option. But depends if I can find the right size diameter)
- Rat tubing
- Drainpipe tubing
