This is a small case for any T-130 toroid project. It is very small yet protects the toroid from contact with outside conductors and handling. Once printed the case can be drilled to accommodate connections as needed. Or drill holes can be added to the model before printing.

There is enough room for windings and the core fits in nicely. The cover snaps on and remains tight in my builds. Perhaps this could be expanded to other size cases but I have not tried that as yet.
