Sleek, Minimalist Design

Engineered with a simple, utilitarian aesthetic, this keychain blends effortlessly with your everyday carry (EDC) setup. It strips away unnecessary bulk, featuring a flat, clean profile, a standardized attachment loop, and elegant 0.5mm dual-chamfered edges that eliminate sharp corners and give it a premium, polished feel.

Preloaded with Popular & Personal Currencies

The script comes preloaded with global standards and specific currencies closely familiar to the author, ensuring precise dimensional accuracy right out of the box. Select your region from the drop-down menu to automatically match the exact diameter and thickness required by local cart locking mechanisms:

- Up to 3 Lines of Text: Emboss any message, name, or phone number you want. - Dynamic Smart Layout: Leave Line 3 blank, and the code automatically shifts and re-centers a clean 2-line layout! - True-to-Size Embossing: Lettering is raised by 0.4mm or cut out by 0.4mm or none. - Granular Tweak Sliders: Easily scale font sizes, shift text coordinates (X/Y), or manually override the baseline coin geometry to adjust for individual printer shrinkage. Print Recommendations:

- Orientation: Print face-up on a smooth PEI sheet to make the embossed text stand out sharply. - Perimeters: Use at least 2 wall loops to guarantee solid structural strength around the key ring attachment hole. - Text Limits: When choosing smaller coins (like the Australia A$2), reduce your character count or use the text scaling slider to ensure your letters don't clip outside the rim. - Material: PLA
