Hopefully the final iteration of this: https://poal.co/s/3dprinting/741910 I gave up on the print-in-place experiment in favor of having something that works and is robust.

Now to print off a dozen and test with the first batch of CTs.

The little disc is a "spring" printed from TPU 70A (Recreus Filaflex). It goes under the coil for some give. Dimensions in mm: 24 wide 26 deep 16 high.

Customer specific project, they make industrial drive systems, don't know much more.

After wrapping, cutting and soldering the wires, the CTs are transferred into their real housing which is then filled with casting resin. These boxes are just to locate everything until the transfer.

Seems a bit much just for shipping material. I assume there was some big problem that made a clever solution necessary.

The transfer happens right away. It's just a bitch to work with this thin wire and have everything flapping around in the breeze. No bueno for accuracy and repeatability and the final housing doesn't lend itself to accomplish any of the previous steps.

We're probably going to need at most a couple dozen of these, they're reused right away after the transfer is done.
