A celestial earring cutter set for polymer clay: a crescent moon, a sun, a star and a sparkle.
Celestial earrings in four cutters: a 32 mm crescent moon and a 28 mm sun that punch their jump ring holes as dangles, and an 18 mm star and an 18 mm four-point sparkle cut plain, as studs or as the small top piece above the moon. Good for celestial and witchy jewellery, gifts for astrology lovers, night-sky collections and festival earrings. The pieces come out 29 x 32 mm (crescent moon), 28 x 28 mm (sun), 18 x 17 mm (star) and 18 x 18 mm (sparkle).
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. The crescent moon and sun cutters have a small tube inside that punches the jump ring hole in the same press, about 3.2 mm across; the 18 mm star and 18 mm sparkle are cut plain, for a post glued on the back or a hole where you want it.
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.
Mix a pinch of gold or pearl mica powder into a deep blue clay for the moon, and brush gold leaf flakes onto the star before baking: the classic night-sky pairing.
Shown as a 3D render of the four printed cutters and the polymer clay pieces they cut, not a photo.
Print each file as exported: the rim flat on the bed, the blade pointing up, no supports.
Condition the clay until it is soft and roll it 2 to 3 mm thick on a tile or baking paper.
Dust the blade with cornstarch, or lay cling film over the clay for rounded edges.
Press the cutter straight down with a fingertip on the rim, wiggle it a little, and lift.
Push the clay plug out of the hole punch with a pin before the next cut.
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.
Let them cool, sand the edges, varnish if you like, and add jump rings and ear wires or glued posts.

Cut the 18 mm star or sparkle as the top piece, pierce it at its lowest point with a needle tool, and hang the crescent moon below it from the moon's punched hole with a 6 mm jump ring. Glue a post to the back of the star for a stud-and-dangle earring.
At 18 mm their points are too narrow to keep 1.6 mm of clay round a 3.2 mm hole, so they are made as studs and top pieces. If you want to hang one, pierce a small 1.5 mm hole near a point with a needle tool before baking.
In the thick upper part of the crescent, back from the tip, so the moon hangs as a tilted crescent opening to the right. For the second earring, turn the cut piece over before baking and it opens to the left.
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.
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.
