Even a 40 years old, Tektronix A6303 current probe is still very useful and top performing current probe. When the probe is available in many online auctions, the calibration fixture for it
/067-0865-00/ is relatively rare and hard to obtain.
This fixture is not a must tools to perform the calibration process, but is very convenient and make the life easy.
Since i own few of those probes i decide to replicate the original fixture based on the original Tektronix documents and some approximation based on the available literature and photos.

The only question here was the position of the current conductor. Based on all the photos i have, it looks like in the original design this stud touching the internal face of the transformer, limiting that way probe movement. In my design i allow for a small clearance.

On the link you may find the original solid works files /pack and go / as well parasolid and .step export of the flathern part, and pdf with BOM.
