See other sections of this tutorial for instructions on folding other unit variants and connecting them.
This big family of BBU units groups together those tiles which are not flat but have some elements which stick out from the base.
All tiles in the family
|Code||Name||Finished look||Front||Back||Crease pattern||Description|
|G10||Uses D10 tile as a base.|
|G13||A useful modification is to first fold the four corners, thus forming the bottom and top flaps, and to fold the sides as a next step. The upper flap formed this way seems to be easier to fold in a straight clean crease than the original design.|
