Step 7: Vents and Door

Vents can be cut into a triangle with a flap to cover the hole and a stick to prop the flap.  Make a BCC #1 or BAA #10 for the flap.  The flap is removable using velcro so that it doesn’t get crunched when the segment is folded.  The flap for the vent is held open by a thin bamboo garden stick, with the nodes of the bamboo serving as convenient stops for holding the flap up.   I made a small notch to hold the pole at the vertex of the opening.  On the triangle with the vent hole, you will need to adjust where you score your B edge in order to make room for the second tab of the cover flap.  This is a good step to practice on your cardboard model first.

The door is a variation of one of the base hexes, and it is actually detached from the neighboring half-hex.  You will cut the 9-piece segment for the door a little differently from the other 4 - see the diagrams and the cutlist. The hinges are made to allow the door to fold up and out for a diamond-shaped entry - no crawling to get in.  To give structural strength to the doorway, 2 of the 6’ poles get re-purposed into supports, and extra clips are placed on nearby tabs.   Extra tape around the joints on the outside also helps.
