I was inspired by MrBeaver’s magnetic replacement of the alligator clip on the probe and decided to make my own version, details below if your interested.
Cross section of assembly - wire soldered to top magnet, super glue around edges of both magnets glued into PLA 3d printed(FDM) housing. Housing filled with epoxy from top for wire strain relief
Threaded wire through housing and soldered on magnet (magnet will partially de-mag from heat). I decided to solder to a magnet because it has a nickel plating that the solder will stick to well
If you’re having issues with de-magnetization or tin not sticking to the magnet (depends on the coating), you can try soldering to an iron washer and sandwich that between the two magnets. Or go the no soldering route and stick a stripped wire in between, then tighten the whole thing with some glue.
Beginner Question - How do you get the magnet to stay on the L bracket rather than the router when you pull it away? As you can see, I tried to copy your setup with a small neodymium magnet I had lying around, but when I pull on the clip, the magnet stays on the collet nut. (I tried putting the magnet on the inside of the L, which solves that problem but then the connection is not strong enough to reliably hold the bracket onto the router. Hot glue maybe?) Thanks.
