QR Code Generator for 3D Printing - Generate custom 3D printable QR code tags as STL files

by•
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.

Hey Product Hunt! I built this because I wanted to 3D print a QR code and every tool I tried was either paywalled, forced a signup, or handed me a static STL I couldn't modify. Half the time the mesh wasn't even watertight, so the slicer would complain or the print would come out weird. 3dprintqrcode.com is my fix for that. It runs entirely in your browser and nothing gets uploaded anywhere. You paste a link (or any text), tweak the config until the preview looks right, and download the STL. That's the whole thing. A few things you can actually control, since most tools don't let you: Pick a size preset or set your own dimensions Adjust base height and QR height separately, so the code stands out in relief Add a hole if you want to hang it on a keychain or lanyard Drop a label underneath with a custom font size Add an icon in the center (scan-safe, won't break reading) Invert it, round the corners, whatever you need The part I spent the most time on: watertightness. I tested the generator across 700+ configurations to make sure the mesh is always clean and printable, no matter how weird your settings get. You shouldn't have to babysit the slicer.
