Thanks Midnightsun!
I have a 3D printer, but for a few bucks more, I prefer something ready made, and coming with a storage case.
Any recommendation would be welcome!

What the puck?

What the ? Why is the puck not sitting flat on the underbody?Me too... gone mine on Amazon. They deform like hell though. Gonna have to get the hard kind, like the red ones listed in this thread.
Are the side clearances different on the Fremont and Austin cars and the structural pack/
On my Fremont car, the pucks sit flat.

Looks like their are some cheap soft rubber ones that hit the market as of late. They used to be all very hard rubber like a hockey puck with no deformation whatsoever.

Yup, gotta test mine. This is either FUD or really cheap crap making the rounds.
The puck plugs into the lift point. Pretty hard to screw that up. They simply deform. Going to get some stiffer ones.

Yeah, I thought of that. Easy enough. Just wanted to confirm that it isn't supposed to be lifted by the center post of the puck.
Thanks zoomer!

Yes. I am confirming what @fholbert said earlier, upthread.
For those of you who have the 279 mile range, Model Y AWD, manufactured at Austin (with an "A" in the 7th-character-from-the-last in the VIN) during 2023 ...
The Potauto lift pucks, which claim to be 20 mm in diameter across the puck protrusion, WILL NOT FIT. They are not, in fact, 20 mm as received, and as I learned in modifying the aluminum puck, they need to be ~19.5 mm diameter in order to fit the (short-run) 2023 Model Y AWD (279 mile range) that was (to date) only manufactured at Tesla Austin from March 2023 through Sept. 2023, when Tesla removed it from the configurator.

I will write a fuller thread in the next couple days to describe how I hand-filed them and what was required to make them fit.
as well as describe the problem with ONLY this particular model of the Model Y.

I took the puck that came from Potauto and hand-filed the aluminum down to ~19.5 mm in order to fit my Model Y with a structural battery pack.
It came 21.8 mm outside diameter. When I got to a clean 20 mm as measured by the micrometer, it still wouldn't fit. So I took it down to 19.5 mm.

I’ve thought about doing the same, but have been looking for a way to spin the puck to reduce the size. I’d also like to have soft pucks.
Anyone has any ideas?
Take the pucks to a machine shop that has a metal lathe and have them turn down the posts on the pucks to 19.5mm if that is the desired diameter.
I've not touched a puck in 30 years but I bet they would be excellent for this and be soft enough to protect the paint a bit without compressing. I've a 3d printer and want to go this route.
1) The holes in those pucks came from where? They look pre-drilled but I haven't seen pucks with holes
2) Is the plastic guide really strong enough for this? I know most forces are vertical but I assume there is a little bit of lateral once the jacking starts
3) I assume in all these cases the puck is going past the lip of the jack's receiver, right, so that it's basically stabbing them? Most of the jacks I've seen look like this, and I'm not sure these are all big enough to take a 3" puck...?

The holes? I machined those out. Only did it so I could snap them together when stored, not required
Never had an issue with the plastic printed part, really only there to keep it in place
I have store bought ones for the Y, they are identical in size to a hockey puck. Not sure what floor jack you have but I have 2 and both are able to take the puck without getting stabbed.

I rotated the tires on my MYLR last week for the 1st time. It was my 1st time using the pucks too. My puck got a bit indented from the raised points on the jack's metal cup/support, though not bad. Just the same, the jack probably would have scratched the lift point a bit had I lined the jack up directly with the lift point, skipping the puck. I think the pucks are a cheap way of helping double check that I'm lifting at the proper point with nothing slipping.
I actually have 2 jacks and a set of 4 pucks so I lifted an entire side of the car up at once, simplifying rotation. Just lifting the back tire first managed to lift the whole side of the car, including the front tire, but it seemed a bit unstable so I continued to support the front part of the car with my 2nd jack before I actually removed the front tire, though perhaps I could have swapped both tires with just the jack lifting at the rear point. Is that what people are doing when they only use 1 jack during tire rotations?
