ROTATE FREELY CAMLOCK CONNECTORS

I've found that in the original design(https://www.printables.com/model/461256-shopvac-50mm-camlock-connectors-with-magnetic-catc), sometimes the vacuum hose occasionally gets stuck, especially when using tools like a tracksaw.

Although it can rotate at the adapter, it seems to be insufficient. If the vacuum hose could also rotate freely at this end, it would greatly increase flexibility. Therefore, I believe this design can be improved in this aspect.

If you need to replace hoses of different sizes, you no longer need to reprint the entire component, you only need to print the inner part.

When installing the hose, you don't need to open the lid; you can simply rotate the middle part.

In order to accommodate larger-sized hoses as much as possible, the overall dimensions are slightly larger than the original design, which means the adapter in the original design is not compatible.

Download adapter and mid part stp file, that you can edit it to fit your tools and hoses.
