What is Stamp Maker (Koolm)?

Stamp Maker by Koolm is one of the most popular customizable models on MakerWorld, with more than 23,000 likes, 15,000 printed makes and over 160,000 customizations. It turns text, an emoji-style icon, a mix of both, or your own SVG file into a stamp design with a screw-on handle.

You open MakerWorld's online customizer, pick the content and stamp shape, then adjust size, fonts, colors and edge treatment before exporting a 3MF or STL. The author suggests lightly sanding the raised face so ink holds better and impressions look cleaner.

It suits crafters, teachers and small businesses who want a personal stamp for cards, packaging or stationery. It is designed mainly for ink pads; for dough, clay or soap, the Customizable Text Stamp by Yumi_Raven is built to press impressions. A free MakerWorld account is needed to customize and download.
