Most QR-to-STL tools are clunky, paywalled, or give you a file you can't tweak after. This one's different, open it in your browser, type your link, start adjusting. Pick a size preset or go custom, set base and QR heights, add a hole for a keychain, drop in a label or icon, round the corners. Every STL comes out watertight, tested across 700+ configurations, so your print won't fail halfway through. Free, no signup, just download.
