Paperware - castle
he six towers are all identical. So if you know how to build one, you know how to build all.
The tower walls (Part T1)
When 21/23 are cut the three/six resulting flaps are folded inside. This will form the opening/s for the castle walls.
The folded parts on lines 15 to 20 can be glued to the "Inside" of the wall, but it works as well if there is just a "sharp" fold.
The part right to line 6 has the brick patter, but it is a flap nonetheless. There is no gluing other than the foldings along lines 15 to 10 if you chose to glue them.
The parapet (Part T2)
The parapet flaps are glued to the small in folded wall sides one by one. When you do this take care that the rectangular portions at line 8/10, 11/12 and 13/14 lie below the folded sections on lines 15/16, 17/18 and 19/20. Every time you glue a flap the tower form will get closer to an hexagon. Try to glue them in a way that the inner wall is rectangular to the parapet floor. The more exact this is done the better the hexagon form and the less gaps between the wall sections. The picture above shows the work in progress.
When you glue on the last flap than also glue together both ends of the tower wall by using the flap which is made of the part to the right of line 6.
Inner floor (Part T3)
Now glue the part inside the tower. Be careful that the cut out sections are aligned with the wall sections that have the in folds.
The easiest way to get an even and straight inner floor is to glue the part so that the flaps are flush with the tower base and the floor itself is set correspondingly. The advantage of doing it that way is that the flaps can be adjusted easily and all flaps have a common base to get aligned to.
