I made this Kanji Nihon stamp for fun. It is a quick print and easy to fix to a dowel. I was unable to upload a modifiable Tinker Cad model but it is really easy to make it say anything. The stamp quality is not very clean. It looks more like a wood block stamp. If you are looking to make a unique stamp I could probably help. A flexible filament would probably be best but I haven't used it yet.
