That's doable; even if it was some time ago, I remeber that there were 3 "definition" options in the QR generator I used for some trials. For the model, I simply used the first one I found on a block explorer, but afterwards, I did some digging to see how good an idea it could be to sell crafted QRs.

Sounds like a great idea, please share some pics once it's finished!
I will try to find a way to make it smaller.
sure, will share it here when it's done.
IDK how to apply epoxy, but my partner, youtube.. will help me with this
it would be even better if the QR code can be simplified, so it can be smaller.
qrencode version 3.4.4

-l {LMQH} specify error correction level from L (lowest) to H (highest).
I tried all options, and even the lowest still has error correction: it still works if I cover a small corner of the QR. According to
Wikipedia, error correction goes from 7% to 30%.
Instead of reducing error correction, you could try to add a Lego Bitcoin logo in the middle.
This seems like a good activity to do with the kids today
I tried with 2 phones, and only one (the oldest) could scan the Lego.
what if I use a link shortener to simplify the url/text before it's generated into a QR code?
maybe, there is a secure decentralized text/link shortener
