Bill of Materials

You will need:

• M2 × 3 mm Screws, DIN 912 / ISO 4762 (optional)

• A small amount of glue

• For earrings:

  • Flat Pad Earring Posts

    • Ø 6mm (regular size)

    • Ø 4mm (smaller size)

  • Silicone or Butterfly Earring Backs

• For pins:

  • Pin Backs and Clasps

Instructions

Each earring or pin consists of:

• 1 hold

• 1 screw (M2 or printed, see below)

• 1 earring post & back (for earrings)

• 1 pin back & clasp (for pins)

At the regular size (100% scale), the holes in the holds are designed to fit M2 × 3 mm screws (DIN 912 / ISO 4762).

You can print screw heads as an alternative (for other scales or simply for lighter earrings, so you can't blame the extra weight for not sending your project).

Glue the screw or printed screw head into the hold.

Let the glue dry.

Then glue the pin back or the earring post onto the back.

Smaller variant

The smaller variant is simply scaled to 80% (both the hold and the printed screw head).

When scaling the model up or down, the hole will no longer fit an M2 screw, so using the printed screw head is highly recommended.

For earrings, you should choose the earring post size according to the model scale:

• Ø 6 mm flat pad posts are a good fit for the regular size (100% scale).

• Ø 4 mm flat pad posts are better suited to the smaller variant (80% scale).

Printing recommendations

• Use a 0.2 mm or 0.4 mm nozzle 

• Use 0.08mm or 0.12mm layer height for the Holds for best results, as the model includes many rounded surfaces and gentle slopes.

• Use 0.20mm layer height for the printed Screw Heads.

• Enabling the Arachne wall generator helps with the screw hole.

• Enable the Fuzzy Skin setting in your slicer for a more realistic climbing hold texture.

  Recommended settings:

  • Fuzzy Skin Mode: Contour

  • Fuzzy Skin Point Distance: 0.6mm

  • Fuzzy Skin Thickness: 0.2mm

• Print on a smooth build plate (smooth PEI or similar).

• If you experience adhesion issues, make sure your build plate is thoroughly cleaned.
