✳ 68 STAMPS · A TRAY · A LID · STL + 3MF
Pottery stamps
from any font.
Drop in a TTF or OTF and this page builds a printable stamp for every letter, checks each one against the print rules, and writes the files. The font never leaves your browser, and neither do the models.
Kalam Bold, by default.

WHAT YOU DOWNLOAD
One zip,
everything in it.
The complete set is 68 stamps, a tray that holds all of them, and a lid that slides shut. Every part is written twice, once as STL and once as 3MF, so it drops into any slicer.
- 01STL and 3MF, one file per part
3MF carries millimetres and orientation; STL is there for slicers that prefer it.
- 02A tray and a sliding lid
68 pockets in a 10 × 7 grid, each the shape of its stamp and labelled with its character.
- 03Printing and pressing guides
Orientation, supports and clay release, in two markdown files.
WHERE THE WORK HAPPENS
No server. No account. No upload.
The geometry is built by a WebAssembly kernel running in a worker in this tab — the same kernel a desktop CAD tool would use, compiled for the browser. There is no backend to send a font to, which is also why the site is free to run.
- Your font stays here
The file you drop in is read into memory and parsed in the page. Nothing is sent anywhere, because there is nowhere to send it.
- The models are yours
The STL and 3MF files are written in the tab and go straight to your downloads. What you make with them is your business, subject to the license of the font you used.
- Nothing is kept
No accounts, no cookies, no analytics, no third-party scripts. Close the tab and nothing of yours is left behind.
HOW IT WORKS
Three steps, all of them on your machine.
Build the set.
Every letter is checked against the stroke and wall rules first. One that cannot be printed is shown with the rule it failed and left out of the zip.
Print and press.
Print the set, test one letter in clay, and raise the weight if a stroke closes up or a tip comes out too fine.
Start with a test print. Fit and clay release depend on your printer, filament, and clay; no set from this generator has been physically verified yet.
