Written assembly guide
- Lay out the 12 labelled pieces and form the small central cross shown in the first stages.
- Add matching arms from opposite directions so the structure remains balanced.
- Fit the middle pair through the open channels and gently square the core.
- Turn the assembly over at the marked turnover stage.
- Add the final outer pair from opposite sides and slide them inward until the diamond is symmetrical.
