Hi, does anyone know if there are files available for retainers for the Melexis hall sensors used in the Tesla SDU?

I've seen them on Westside EV's page here: https://www.westside-ev.com/store/p/bui ... verter-kit and Damien mentions he might be able to supply them at some point in the future: https://openinverter.org/forum/viewtopi ... 858#p86858

Hey @MoonUnit,

I designed the current sensor supports primarily to protect the sensors from bending or damage during shipping, they don’t actually “retain” the sensors in normal use. I wanted a way to ship boards with pre-soldered sensors without them being bent/damaged, and this was the best solution I could come up with.

They aren’t required for installation or operation of the board. If you’re building your own board and soldering the sensors yourself, there’s really no reason to include them unless you plan to ship the board afterward.

Thanks for the reply. I have yet to solder my board and figured these would be useful but given what you've said it sounds like I won't need them.
