About this generator

The STL Playground Medallion Builder makes a bold, layered medallion to wear on a chain, a lanyard or a ribbon, or to put on display. It is made for team spirit, esports, events, giveaways and gag gifts. You upload SVG artwork, or use emoji and text, and STL Playground's PNG to SVG converter helps with logos that are not a vector yet.

The base can follow the outline of the artwork or take a fixed shape, with adjustable border and background layers, glow layers, and a loop for hanging it that you can resize. The layers are made for multicolor prints with simple color changes, so a multi-material printer is not needed.

Designing and previewing work without an account. Downloading needs a free account with 100 credits a month, and every download costs 10 credits, so you get about 10 files a month for personal use. Selling prints needs a paid STL Playground plan.
