Steps

  1. Make the plate

    Add a Box with Size 70 × 28 × 4 mm. Pick a bright colour.

  2. Make the key hole

    Add a Cylinder, make it a Hole, Size 7 × 7 × 10. Set its Position to X −28, Y 0, Z 2.

  3. Group the hole

    Select the plate and the hole (Shift+click) and press Group.

  4. Add the star

    Add a Star with Size 14 × 14 × 6. Place it at X 10, Y 0, Z 6 so it sits on the plate. Give it a different colour.

Why it works

Thin parts print fast. Keep a plate at least 3 mm thick so that it is strong.

Challenge: Add your initials using small boxes, or add a second star.

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