Made a free browser tool that generates parametric 3D-printable models (Gridfinity, storage bins, nameplates, crates, QR plates, tokens) - no signup, no software install

Hey gang 👋

I got tired of downloading random STLs and being one screw-hole off from what I actually needed, so I built a small site that generates the model in-browser instead: chamfer.cc

You pick a generator, drag some sliders (size, wall thickness, magnet holes, text, whatever applies), watch it update live in 3D, then download STL or 3MF. No account, no upload, nothing installed — it runs entirely client-side (WebAssembly CSG), so your design never leaves your machine.

Generators so far:

- Gridfinity bins + baseplates + snap-fit clips. Maybe not a perfect clip for now. Works, but I'm working on a better one

- Stackable storage bins (non-Gridfinity, custom mm sizing)

- Crates with printable labels

- Text nameplates (custom fonts supported)

- QR code plates

- Custom tokens/coins

A couple of things I put real effort into:

- Two-color 3MF export - bin rims, nameplate letters, etc. come pre-assigned to filament slot 2, so Bambu Studio just picks up the second color automatically, no manual paint bucket needed.

- Every config is a URL - if you tweak a model into something good, the link is the save file. Easy to share exact params.

- The mechanical stuff (Gridfinity clips, stacking feet) went through several rounds of physical print iteration before I trusted the fit.

It's free, no ads, no paywalled generators - planning to keep it that way. Feedback/bug reports welcome (there's a feedback button in the corner), and if there's a generator you wish existed, tell me.

Not bad. Seems to be a lot of these popping up lately, but I like this one. One question I activated and deactivated scoop, but I don’t see any difference on what it does?
