Hi Product Hunt! I'm Kostya, a developer from Ukraine. 3D printing is my hobby, and I like to make gifts. Printing a personalized gift used to take me three sites: one to turn a picture into a stamp by picking the areas to keep, another to convert it to SVG, and then the slicer to put it on the model. Too many steps for something printed once, and none of them could put the picture on a curved surface. So I built a page where I could put words or a picture on a 3D print in minutes. The first problem it solved was the curved surface, and that was the hardest part to get right. Now you just drag the stamp to where you want it, and it wraps onto the shape — no extra steps. Then I added a small 2D editor, so you can pick the area of a picture right on the stamp. After that I decided to publish it and make it free for everyone. Everything runs in your browser, so the domain is my only running cost — nothing compared with what it can save other people. Accessibility got special attention. Every control has a name, every result is spoken, and Braille follows the signage standard. I want everyone, whatever their eyesight, to be able to make a personalized 3D model. To make the first steps easy, there's a learning cube: The surprise came this month: because the page is fully accessible, an AI agent can use it the way a keyboard user does. I asked Claude in Chrome to make a gift. It designed a vase on its own, opened it here, added a heart and the words — and every mark stayed editable. There's a video of the whole model being ready in 7 minutes. Thank you to everyone who tried the tool, tested it and nudged me toward new ideas. I would love to know where it's most useful for you and what I should fix.
