Made with our free stamp maker, not modelled by hand: we typed APPROVED into it, picked the rectangle shape at 64 by 24 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

Which ink works with the approved stamp?

Any standard stamp pad: water-based for paper, or a solvent or pigment pad if you stamp glossy card or envelopes. Red is the classic APPROVED colour. Press straight down with even pressure and lift straight up, without rocking.

Can I change the word on the approved stamp?

Yes. Open the free stamp maker, type your own word, pick Rectangle and Bold & Blocky, and switch on the border ring: that is exactly how this one was made, and the settings are listed in the zip.

Can I print the approved 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.
