Intro
This is a manual valve actuator for some types of EXV's or EEV's. I found the official ones to be expensive and overtime the magnets can come loose. This model will encapsulate the magnets to prevent that. I created two models; one with a keyring slot and one without. So far I have only tested it on Carel EEV's used in Heatcraft evaporators.
Assembly
The trick is the six magnets need to have the north polarity facing out. Then add a pause at layer "111" and add a little superglue to each magnet when inserting. The superglue is to prevent the magnets from adhering to steel/hardened nozzles when printing is resumed.
The magnet polarity can be verified with a compass and Clough42 has a good video on how to determine polarity, linked below.
