This is a jack pad for a Tesla Model S & Model X. It has cavities for attached magnets, but they are not necessary. This can still be used without magnets in it.
I used these magnets:
N35 Strong Round Disc Ring Magnet Rare Earth Neodymium 20mm x 10mm
You need 2 per jackpad.
You need to insert the magnets as it prints after the cavity is printed but before the first layer of the cavity starts...so either you pause your printer on the correct layer or you have to be quick as a rabbit and drop them in the hole at the right time. Make sure you are not using a steel block or other magnetic heating block or nozzle. You must use.
