About CodesToSTL
CodesToSTL is a small, free web tool that turns a Spotify link into a 3D-printable Spotify code keychain. You paste the URL of a song, album or artist and generate a preview straight away.
Options are kept short: rounded or squared shape, a hole at the top or none, a total length of 6, 8 or 10 cm, and low, medium or high relief for the code bars. The result downloads as an STL. It is an unofficial, non-profit tool, and its terms say the generated designs are for personal and hobby use only, not for sale.
It suits anyone who wants a music gift in a couple of clicks without an account. For extras like album art slots, multicolour setups or QR codes, you will need a larger generator.
