Yesterday I wrote in topic stainless seed plate and came to the conclusion that it should have been posted here. Which is exactly what I'm going to do now.
I decided to add visibility to my yesterday's idea and refine it a little, diluting it with my comments on this matter.
I took the already known washers (the most common metal ones, not inox), a couple of nuts and a threaded rod. You can vary set according to their availability in your toolbox or store.
With this mini-experiment, I want to clearly show that 4 words can be applied to 1 washer. 2 on one side and 2 on the back. If reduce the number of letters to 4 (this is enough to identify the desired right word and restore seed-phrase). There is still space for numbering the puck so as not to make a mistake with the word order.
In principle, if you use slightly larger washers, you can fit more symbols.
In order to place 24 words (the first 4 letters), 7 washers will be enough. On 5 washers , apply 4 words, and on 2 washers, only 2 words on one side for each (when assembling the storage, place these 2 washers on 2 sides, clean sides out). This will hide the image.
Also, nothing prevents you from combining 2-3-4 seed phrases into one construction, this will be 12-18-24 washers.
Now about my symbols in the pictures. These are arbitrary symbols to show their legibility, applied with a regular screwdriver (hard alloy is needed). As I said, the thickness of the washers is 3 mm, and this allows you to apply text on both sides. There are no dents or marks on the back side. This can be seen in the pictures above.
I would like to add that I don't invent what was invented by fillippone, but only slightly modernized in order to make the storage more compact.
In my opinion, the option with pucks seems to me more interesting - Securing Your Seed Phrase with Washers. But with a slight correction (saw in your thread): put only the first 4 letters of each word on the washer, which will allow to fit 2 words at once (the first 4 letters of each) on 1 washer. This will reduce the number of washers to 12 (in the case of 24 words) and to 6 (in the case of 12 words). This is appropriate if you strive to reduce the object.

The washers are 3mm thick (I'll come back to this later) and about 37mm in diameter.
In my case, the rounded side of the nuts fits perfectly into the hole of the washers, so I screwed them the other way around.

In the pictures, the front and back sides of the same washer.

This is what it looks like assembled. As you can see, there are 12 washers here (Can accommodate 2 seed-phrases of 24 words each).
