I'm thinking of making a cage made up of two or three bin cages connected by tubes, the tubes are going to be at least 4 inches in diameter. any suggestion are appreciated.
For guinea pigs? bin cages are only suitable for hamsters, mice, gerbils and maybe rats. even having a few connected do not come near the recommended 7.5 square feet a guinea pig needs and that is the minimum a guinea pig needs. most of us here have more room than that. https://www.guineapigcages.com/ shows you the minimum cage sizes for guinea pigs and gives you ideas on alternative ways to make cages if you cannot get the materials for a C&C cage.
@Megaredize I can buy bins that are 2 ft x 1 ft, do you think i should connect 5 of them? i didn't buy the guinea pigs yet, i usually look up something before buying it.
They need a minimum of 7.5 square feet of open space, preferably 10.5 sq ft. Connecting them with tubes don't provide an open single level unfortunately. The bins are also much too narrow, which can cause dominance issues & will prevent them from being able to run laps & turning corners.
You can use a cheap regular bookcase as a sturdy cage, it's really common here in Sweden.
You'd need to waterproof it with something like thick pvc/plastic tablecloth which will need replacing, but it's fun to change it with the seasons.
You may also need to support the back/bottom with some cheap plywood, and many prefer to cut a side out & replace it with plexiglass.
I believe Ikea has the same products all over the world, but any bookcase with appropriate inner dimensions would work. The Billy bookcase is the most popular one here because of the price & generous measurements, it's about ~15 sq feet. The price differs depending on color.

You can put in one shelf, drill a hole/saw through it & use it as a kitchen area if you can't use coroplast:
