I can do other designs if you have a request. I charge $5 per hour for 3D modeling, I could model most things you want on a toast stamp in 1 hour.
I can add a bitcoin address to any toast stamp for an additional $0.75 usd
It will work in a toaster oven as well, I have made Pizza stamps and they work in a pizza oven too, you just have to make sure the stamped side is facing the heat source.
I will ship world wide, Free to the USA. Let me know where you want it shipped if your outside of the USA and i can get a shipping quote for you.
