After reading this thread, I came up with the idea to simplify jig. Undoubtedly,
n0nce's Steel Washer Backup jig is convenient and useful, but there may be cases when there is no time to search or create jig. In this case, my downgrade (because the design is simplified as much as possible) can perform its function as a template for stuffing letters just as well.
Wow, good job! I really like this idea.
Of course, you can't help but like this idea, since it's basically your idea.
I just simplified it and slightly changed it, making it accessible even to a schoolboy.
If there are difficulties with fixing the position of the stamp on the template, then you can use several layers of a large circle (gluing them) and / or using thicker cardboard (thin is easier to cut into shape).
I was about to say: One layer will be suboptimal, because (you'll notice this when you try with real stamps), you tend not to hold the letter perfectly straight without a jig, resulting in letters being deeper at the top than at the bottom for instance.
I've got an example picture here, and it's even harder with larger letters:
However, if you were to cut out like 10 of those disks and glue them together, it might hold the stamp straight enough (or help you hold it straight, since the cardboard would be easier to bend by hammering than bending the plastic).
Yes, I assumed that the layer in my case is too thin and in real use with a stamp, a thicker thickness is needed. This is a kind of prototype, which aims to show the general concept and requires further development for practical use.
Yes, in my case there are few sheets of cardboard. More is needed to better fix the stamp. I think the optimal thickness will be ~ 5-10 mm.
You can make a similar stencil on a 3D printer with variations to your choice.
Another option that is cheap and quick to manufacture (if you have the tool) is laser-cutting. Multiple layers of plywood glued together should work really well. And would give the lateral stability that I don't yet fully trust in when using cardboard.
Oh yeah, laser. How did it not occur to me. Can even cut a template out of plywood and it will be durable and regular in shape.
P.S. Sellers are surprised by the sudden demand and hype for washers. They say they are expected to be in short supply.
I'm already heavily invested in the washer market! All these posts I'm writing are pure market manipulation.
Well, I didn't assume otherwise and was sure that there was a vested interest here.
The main difference I believe, is that re-stamping is hard without notches. I had to do it since my material was quite hard, the table I used was quite soft (absorbed a lot of the impact), and my letters are pretty large - so imprints weren't always deep enough for my taste.
How about using washers from another metal? Softer, for example, aluminum. This metal is not subject to corrosion due to the oxide film, which is quite resistant to weathering. The melting point is also not very low. But the main advantage is ease and pliability in processing.
~ cheap ~ to manufacture ~ is laser-cutting.
I can think of
great ways to store seed phrases in steel plates with laser cutting, but I wouldn't assume it's cheap.
You misunderstood. A laser can be used to make a template. For example, from plywood, something like here.
The perfect place to store seed-phrase, right? Ok, at least cute for sure.
Wood will be stronger than cardboard and hold its shape well, almost like plastic. Also, the laser burns out the edges of the plywood, which strengthens the wood in these places. So, I think the strength is quite high (in theory).
Can order along with the details for the template and other elements, so as not to raise questions, why do you need this product. Lose them among other elements. Something like bitcoin-mixer. No one will guess why you need a few circles in a common pile of details. And already at home you can glue them (as in my post with cardboard) or fasten them with bolts (or other ways ) and apply them to your needs.

Sorry, I meant creating the tool with a laser cutter.
A small 30W laser cutter should be available for around $200, so it might even be cheaper than buying a 3D printer. But of course you can only do plywood cutting and cardboard with those weak diode lasers. In a pinch though, it would allow you to make a few disks and glue them together. In fact, even the original 'full stamp' design should be laser-cuttable in multiple layers with minor modifications.
As you mentioned, this would still circumvent the issue of not wanting to have the seed phrase in any sort of encoding on any sort of electronic device.
While I was writing the answer to LoyceV, you already outstripped me with an explanation.
The laser can't cut plastic from a piece, can't it? And how about engraving washers with this laser? Engraving depth not enough?
