What is the thought process here?
The Friggebod is 15 m2, about 3.3*4.5. Flat roof, higher on one long side. Plenty of air vents on the long sides under the roof (between the roof beams). Paneling on the outside and plywood as the inner wall (70 mm in between). No insulation.
The kit came with 2 vent grilles, but only for the outer wall. And they're small: 75 mm in diameter and about 100*100 on the plate outside.
I'm thinking of buying two "proper" vent grilles, maybe 125 * 125 (whatever diameter that gives), with insect nets. But how do you do it inside the shed, i.e. in the plywood?
Drill a hole there as well?
Then with some type of pipe/flexible conduit from the outer part to the hole in the plywood?
And what do you put inside as the frame for the drilled hole?
Tips on "hitting the mark" when drilling the outside and inside parts (or is there something that drills through both at once)?
And placement. Maybe place these on the lower side, so the warm air comes in there and is led upward and through the shed towards the outlet on the higher side? Short or long side?

Best answer
Take a long narrow drill and drill vertically/horizontally as a pilot hole. Then use the cup drill and drill from outside and inside.
You want airflow diagonally both in width and height.
