Modular Guinea Pig Tunnels

I designed this modular guinea pig tunnel system in Tinkercad. The snapfit connectors should allow most orientations. I'm in the process of test-printing them but welcome to suggestions about how to improve these.

These are designed not to need rafts, although a brim on the long tunnel might be an idea. I suggest printing as orientated.

The first set of these are too small for guinea pigs. I've updated the files so they should fit plump guinea pigs like ours!

These are harder to print than I'd imagined so I'm still updating the files.
