Made with our free stamp maker, not modelled by hand: we typed TOP SECRET into it, picked the rectangle shape at 70 by 22 mm with a 2 mm border ring, and left everything else at the page's defaults. The zip holds exactly what the tool gives you: a stamp plate with a 2 mm raised face and a handle that screws into its back, as one STL, and as a 3MF with the face, plate and handle as separate coloured parts.

Shown as a 3D render of the printed stamp and the print it makes on paper, not a photo.

What you need

3
  • A stamp pad in the colour you like (water-based for paper, pigment or solvent for glossy card)
  • About 13 g of filament: TPU 95A for the plate gives the best print, PLA or PETG work too
  • Paper, card, kraft bags or tags to stamp on

How to use it

5

  1. Print both parts as exported: the plate face down on the bed, the handle standing on its foot, no supports.

  2. Screw the handle into the back of the plate until it is snug.

  3. Tap the face on the stamp pad a few times so every part of it is evenly inked.

  4. Press straight down with even pressure and lift straight up, without rocking.

  5. Wipe the face with a damp cloth after use, and store it face up.

Questions about this design

Can I use the top secret stamp for an escape room?

Yes, it is a favourite prop. Stamp the case files and clue envelopes in red, and it looks official straight away. A pigment pad dries slower on glossy paper, so give each print a minute before you stack them.

Why is the top secret stamp so long?

Two words on one line need the width: the face is 70 by 22 mm, so the letters stay tall enough to read. Upload your own text to the stamp maker if you want it on two lines in a squarer stamp.

Can I print the top secret stamp in one colour?

Yes. The STL is the plate and the handle in one file for any printer. The 3MF keeps the raised face, the plate and the handle as separate parts, so a multi-colour printer can print the face in a contrasting colour and you can read the stamp at a glance.
