Geometric polymer clay earring cutter set

Four geometric earring cutters for polymer clay: hexagon, diamond, half circle and triangle.

Four clean geometric shapes for modern polymer clay earrings, each with the jump ring hole punched where it hangs straight: a hexagon (26 mm) and a diamond (32 mm) that hang from a point, and a half circle and a downward triangle (28 mm each) that hang from their flat top edge. Good for modern minimalist earrings, colour-block and terrazzo slabs, office wear and gifts for friends. The pieces come out 23 x 26 mm (hexagon), 20 x 32 mm (diamond), 28 x 14 mm (half circle) and 28 x 25 mm (triangle).

Made with our free cookie and clay cutter generator, not modelled by hand: we drew each shape at its size and uploaded it to the tool, with Cut detail into cutter switched on for the jump ring hole. The zip holds exactly what the tool gives you, one STL per cutter (a 0.8 mm blade, 14 mm tall, with a 4 mm rim to press on, printed rim down with no supports) plus each drawing as an SVG, so you can remake any of them at another size. Every cutter has a small tube inside that punches the jump ring hole in the same press, about 3.2 mm across with at least 1.6 mm of clay round it, so there is no drilling after baking and both earrings of a pair hang the same.

For polymer clay earrings: condition Sculpey Premo or Souffle, Fimo or Cernit, roll it 2 to 3 mm thick, dust the blade with cornstarch (or cut through cling film for soft, rounded edges), press straight down and lift. Bake the pieces on a tile as your clay's packet says, for most brands 110 to 130 °C (230 to 275 °F) for 15 to 30 minutes per 6 mm, then sand the edges, varnish or add UV resin if you like, and fit jump rings, ear wires or glued posts.

The same cutters cut air-dry clay, precious metal clay, fondant and gum paste, and dough for tiny cookies, but once a cutter has touched polymer clay keep it for clay: print a second set for anything you eat.

Geometric shapes show off a sharp edge, so sand them after baking: 400 then 800 grit wet sandpaper on a flat board keeps the edges crisp and square.

What you need

7
  • Polymer clay: Sculpey Premo or Souffle, Fimo, Cernit or any oven-bake brand
  • An acrylic roller or a pasta machine, and a ceramic tile or baking paper to work on
  • Cornstarch or cling film so the pieces release cleanly
  • A pin or a paper clip to push the clay plug out of the hole punch
  • Findings: 6 to 8 mm jump rings, ear wires or flat pad posts, and jewellery glue for posts
  • Wet sandpaper (400 to 1000 grit) and a varnish or UV resin for the finish, if you like
  • About 8 g of PLA or PETG for all four cutters

How to use it

7
  1. Print each file as exported: the rim flat on the bed, the blade pointing up, no supports.

  2. Condition the clay until it is soft and roll it 2 to 3 mm thick on a tile or baking paper.

  3. Dust the blade with cornstarch, or lay cling film over the clay for rounded edges.

  4. Press the cutter straight down with a fingertip on the rim, wiggle it a little, and lift.

  5. Push the clay plug out of the hole punch with a pin before the next cut.

  6. Bake the pieces on the tile as your clay's packet says (most brands 110 to 130 °C, 15 to 30 minutes), never the cutter.

  7. Let them cool, sand the edges, varnish if you like, and add jump rings and ear wires or glued posts.

Questions about this design

How do I get sharp edges on earrings from the geometric cutter set?

Cut without cling film for a crisp edge, bake, then wet sand the edges on 400 and 800 grit paper held flat on the table. Geometric shapes look best with square, sanded edges; cling film over the clay rounds them instead.

Which way do the hexagon and diamond from the geometric set hang?

Both hang from a point: the punched hole sits just below the top corner, so the hexagon shows as a pointed hexagon and the diamond as a long rhombus. For a flat-topped hexagon, turn the cut piece a sixth of a turn and pierce it yourself.

Can I combine the geometric earring cutters with a circle stud?

Yes, a small circle stud over a triangle or a half circle is a classic geometric layout. Cut the stud with a 10 or 12 mm circle cutter, pierce it at the bottom, and join it to the punched hole of the geometric piece with a 6 mm jump ring.

How long do I bake earrings made with the geometric earring cutter set?

Follow your clay's packet, since brands differ: Sculpey Premo bakes at 130 °C (275 °F), Fimo and Cernit at 110 °C (230 °F), for about 30 minutes per 6 mm of thickness, and thin 2 to 3 mm earrings still get the full minimum time. Use an oven thermometer, bake on a tile, and never bake the cutter.

Can I make the geometric earring cutter set in other sizes?

Yes. Every drawing is in the zip as an SVG: upload one to the free cookie and clay cutter generator, set the Cutter size slider (8 to 120 mm) and switch on Cut detail into cutter to keep the hole punch. The hole scales with the drawing, so start from the drawing closest to the size you want.
