Making a custom Gridfinity insert was taking me an hour. Per bin. Snapfinity generates a perfect-fit Gridfinity storage insert from a photograph. Photograph any object on the included calibration board. Computer vision measures it and outputs a custom STL, STEP and 3MF — ready to slice and print. No calipers. No CAD. First print fits. $9.99 · One-time purchase · No subscription 5 min vs 1+ hour manually Mac + Windows both platforms supported How Snapfinity Works Four steps. Zero manual measurement. 01 Print the calibration board Download and print the included A4 calibration board.

No browser, no cloud upload. ⚡ Works Offline Everything runs on your machine. Your photos never leave your computer. Frequently Asked Questions Q. What do I need to get started? A printer for the calibration board, a phone or camera for the photo, and a 3D printer. FDM printers (Bambu, Prusa, Creality) all work. Q. How accurate is it? Typically within 0.5mm on each axis. Accuracy depends on photo quality and lighting — not how well you can use a calliper. Q. What files does it output? STL, STEP and 3MF. All three are included in every export. Q. Does it work for any object? Best results on objects with clear edges. Objects with transparent or mirror-finish surfaces are harder but usually still workable. Q. Does it need an internet connection? Only to download the app. After that everything runs locally — no cloud, no subscription. Q. How many devices can I use it on? One license covers one device.
