Made by hand stamp

MADE BY HAND on two lines in an oval: a small stamp for pottery, polymer clay and leather tags.

3D render of the printed made by hand stamp, face up next to its brown handle, and a round slab of clay with the stamp pressed into it
Clay ~11 g Pro early access

MADE BY / HAND in a bold serif on two lines inside a thin oval border: a small maker's mark that says it in three words. Mark the foot of pottery, the back of polymer clay pendants and trinket dishes, air-dry clay ornaments and leather tags.

Made with our free stamp maker, not modelled by hand: we typed MADE BY / HAND into it, picked the oval shape at 48 by 32 mm with a 1.5 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. The page mirrors the face, so the mark reads the right way round, and flares every raised wall a little toward the plate, which helps the stamp let go of a slab of clay.

Shown as a 3D render of the printed stamp and the mark it presses into a slab of clay, not a photo.

What you need

3
  • Clay to stamp: pottery clay at soft leather hard, polymer clay before baking, or air-dry clay
  • Cornstarch for polymer clay, or a damp sponge for pottery clay, so the face lets go cleanly
  • About 11 g of PLA or PETG

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. Dust the face with cornstarch, or dampen it for pottery clay.

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

  5. Brush clay out of the gaps before it dries, and store the stamp face up.

Questions about this design

Does the made by hand stamp work on polymer clay?

Yes. Press it into the raw clay before baking, with a little cornstarch or water on the face so it releases cleanly, and bake as usual. The oval border makes a neat frame on the back of earrings, pendants and trinket dishes.

How big is the made by hand stamp?

The oval face is 48 by 32 mm: small enough for the foot of a mug or the back of a coaster, and large enough that a 0.4 mm nozzle prints every letter of the serif lettering cleanly.

Which filament should I print the made by hand stamp in?

PLA or PETG, at 0.12 to 0.16 mm layers for the crispest letters. Clay needs a rigid face, so skip TPU, which flexes and blurs the mark. A dry toothbrush gets clay out of the gaps before it hardens.
