01About

Four pairs of Halloween earrings in one download: cream ghosts with open eyes, orange jack-o'-lanterns with cut-out faces and curved ribs, and black and purple bats in two versions, one that hangs from a wing tip at an angle and one that hangs upside down by its feet.

Every charm is 2.4 mm thick, 26 to 40 mm wide, and prints flat in under an hour a pair with no supports. Each has a 2 mm hole for a jump ring and an ear hook; the hardware isn't included. The ghost and pumpkin print in one color. The bats are black and purple through every layer, so they need an AMS or another multicolor setup.

Each pair comes as a Bambu Studio project for a P2S and as STL, and the bats also come with a project for a 0.2 mm nozzle, for finer edges. The license lets you sell the earrings you make.

  1. Open the 3MF in Bambu Studio

    Open it as a project (File, then Open Project). The printer, plate and settings are already saved, so there's nothing to set up. Printing on another brand? Use the STL files with the settings below.

  2. Load your filament

    You need four colors:

    • GhostWhite
    • PumpkinOrange
    • Bat framesBlack
    • Bat wingsPurple
  3. Print

    Print everything on the list below, then put it together.

The bats' two colors run through every layer, so a single filament change can't reproduce them: use an AMS or another multicolor setup, and keep the prime tower. Printed in one color, a bat comes out as a plain silhouette. Keep the scale at 100% so the 2 mm holes fit the hardware.

Printing on another printer or slicer? See the settings

Each pair's 3MF project has all of this saved for a Bambu Lab P2S. Using the STLs on another printer? These are the settings they were made with.

03What to print

8 charms in 4 pairs. The whole collection:

Ghost earringsGhost_Pair1 pairWhite
Jack-o'-lantern earringsPumpkin_Pair1 pairOrange
Bat earrings that hang from a wingBat_Wing_Attachment_Pair1 pairBlack and purple
Bat earrings that hang upside downBat_Feet_Attachment_Pair1 pairBlack and purple

Each one prints a pair. Use its 3MF or its STL, not both. Each bat STL comes as a black file and a purple file: load both together as parts of one object.

04Putting it together

  1. Pick a format per pair

    Each folder makes one pair. Open its 3MF as a project, set up for a Bambu Lab P2S, or use its STL in any slicer, not both. The bat folders also have a project for a 0.2 mm nozzle.

  2. Print them flat

    Decorative face up, no supports, no brim. The ghost and pumpkin are one color. The bats are two colors in every layer, so they need an AMS or another multicolor setup; load both bat STLs together as parts of one object.

  3. Clean the loops

    Let the charms cool before taking them off the bed, then remove any strings and check each 2 mm hole and the edges.

  4. Add the hardware

    Twist a jump ring open sideways with jewelry pliers, pass it through the charm and the ear hook's loop, and twist it closed. A jump ring about 5 to 6 mm across, with wire under 1 mm, is a good start. Hooks and jump rings aren't included.

  5. Hang them

    The wing bats hang at an angle from one wing tip, mirrored left and right; the feet bats hang upside down. No glue anywhere.

Keep finished earrings away from heat that could soften the plastic, and check each pair before wearing or selling it.
