Steps

  1. Add the heart

    Add a Heart: Size 44 × 44 × 6 and a pink colour.

  2. Add the key-ring hole

    Add a Cylinder, make it a Hole: Size 5 × 5 × 10. Position X 0, Y 12, Z 3.

  3. Group

    Select both and press Group. A round hole appears in the heart.

  4. Try the views

    Press Top to see it from above. The hole should be inside the heart, not at the edge.

  5. Export

    Press Export ▸ STL.

Why it works

The key-ring hole must have at least 3 mm of material around it, or it can snap.

Challenge: Add your initial with a small box, or a second smaller heart on top.

All sizes are in millimetres. Type exact numbers in the right-hand panel. Press Export to get an STL file for a 3D printer.
