Folded diamond ornament / LETTER

A good fit for your idea?

Letter and A4 preserve the component dimensions. Choose the sheet you will print, not a different object size.

Materials and construction

Ordinary paper for a first trial; scissors; ruler; a blunt scoring tool; a small amount of paper adhesive.

Before making a batch

Measure several different face edges and the reference line.

Check every letter pair without stretching a seam.

Record any tab collision, open apex or face buckling.

Portrait

Eight equilateral faces: 40 mm edge length.

Five joining tabs: 4.5 mm nominal depth.

Nominal opposite-vertex span: about 56.57 mm before paper thickness.

From file to finished page

  1. Cut the entire connected net, keeping all five lettered tabs. Do not separate the numbered faces.
  2. Score every dashed face boundary and tab hinge. Fold the printed face numbers toward the inside.
  3. Dry-fold the net so all faces meet in a diamond shape. Locate matching lettered boundary edges before adding adhesive.
  4. Join matching edges A through D, applying adhesive only to their tabs. Let each seam set before moving to the next.
  5. Close the remaining E seam last. Keep the model on a flat display surface until all joins have set.
Printing and use notes

Decorative paper model only; not a hanging-load or toy specification.

The unfolded geometry is checked digitally; physical assembly is still required.
