摘要：
A vent 1 comprising a first aperture 10 and a second aperture 12 connected together by a body portion 14 configured to allow airflow therebetween, the first and second aperture being offset in a first direction (height), and wherein the vent comprises an adjustment portion 16 which is adjustable to provide a plurality of different lateral offsets of the first and second apertures relative to one another in a second direction laterally (left or right) to the first direction. The body portion may be elongate in the first direction and the first and second apertures have width in the second direction, with the width of the second aperture being less than the first aperture. The vent may comprise a plurality of adjustment portions adjacent one another (18, fig 5) configured to slide. The adjustment portion may comprise a rotating mechanism (fig 13) having a pair of pivoting elements positioned on the body to permit rotation of first and second apertures, or may comprise a plurality of foldable sections configured to expand and compress so that the body is telescopic (fig 27).

CLAIMS:
1. A vent comprising a first aperture and a second aperture, wherein the first and second apertures are connected by a body portion configured to allow airflow therebetween, the first and second apertures being offset in a first direction;
wherein the vent comprises an adjustment portion which is adjustable to provide a plurality of different lateral offsets of the first and the second apertures relative to one another in a second direction laterally to the first direction.
2. A vent according to claim 1 wherein the adjustment portion is positioned on the body portion.
3. A vent according to claim 1 or 2 wherein the body portion comprises an elongate dimension that extends in the first direction; wherein the adjustment portion comprises at least a section of the elongate dimension of the body portion.
4. A vent according to claim 3 wherein the first and second apertures have a width in the second direction and wherein said width of the second aperture is less than said width of the first aperture.
5. A vent according to claim 4 wherein the second aperture has a width in the second direction of between 75 to 150mm, preferably approximately 100mm.
6. A vent according to any of claims 1 to claim 5 comprising a plurality of adjustment portions.
7. A vent according to any of claims 1 to claim 5 wherein the adjustment portion is positioned at or adjacent the first or the second aperture.
8. A vent according to any of the preceding claims wherein the adjustment portion comprises an extendible mechanism.
9. A vent according to claim 8 wherein the extendible mechanism is configured to extend in the second direction, which is substantially perpendicular to the first direction, thereby offsetting the first and second apertures laterally relative to the first direction.
10. A vent according to claim 8 or © wherein the extendible mechanism comprises a plurality of sliding elements, each configured to slide up to a predetermined distance relative to the adjacent sliding element(s).
11. A vent according to claim 10 wherein the sliding elements comprise frames of four sides defining a substantially rectangular aperture through which air can flow.
12. A vent according to claim 11 wherein the frames each comprise at least a part of a sliding mechanism, for cooperating with, and allowing the frame to slide relative to, an adjacent frame.
13. A vent according to claim 12 wherein the sliding mechanism comprises at least one groove and/or a tab, the groove configured to receive a tab of an adjacent frame and the tab configured to fit into a groove of an adjacent frame.
14. A vent according to claim 12 or 13 wherein the body portion comprises at least a groove or a tab for connection to a frame.
15. A vent according to claim 11 wherein the frames each comprise at least one flange configured to block a gap created by sliding one frame relative to a neighbouring frame.
16. A vent according to claim 11 wherein the frames comprise a pair of panels positioned on either side of the aperture and configured to block a gap created by sliding one frame relative to a neighbouring frame.
17. A vent according to any of claim 1 to claim 6 wherein the adjustment portion comprises a rotating mechanism.
18. A vent according to claim 17 wherein the rotating mechanism comprises a pair of pivoting elements positioned on the body member,
wherein the first pivoting element allows rotation of the first aperture relative to the body portion and the second pivoting element allows rotation of the second aperture relative to the body portion.
19. A vent according to claim 17 wherein the rotating mechanism comprises rotating connection joints between the elongate dimension of the body portion and portions comprising the first and second apertures.
20. A vent according to any of claims 1 to 9 wherein the adjustment portion comprises a plurality of foldable sections configured to be expandable and compressible.
21. A vent according to claim 20 wherein the foldable sections are foldable sections of the wall of the body portion.
22. A vent according to claims 20 or 21 wherein the adjustment portion is adjustable in a third direction, orthogonal to the first direction and the second direction.
23. A vent according to claims 20, 21 or 22 wherein the adjustment portion comprises at least one bistable portion adjustable between stable states to place the vent in different configurations.
24. A vent according to any of the preceding claims wherein the body portion is adjustable to vary its length in the first direction between the first and second apertures.
25. A vent according to claim 24, wherein the body portion is telescopic.
26. A vent according to any of the preceding claims wherein the vent is integrally formed.
27. A computer readable medium having stored thereon computer executable instructions that, when executed by a processor, cause the processor to control an additive manufacturing apparatus or device to manufacture the vent of the preceding claims.
28. A method of manufacturing a device via additive manufacturing, the method comprising:
obtaining an electronic file representing a configuration of a product including, a surface configuration or a volume configuration of the product, wherein the product is a vent according to any one of claims 1 to 26; and
controlling an additive manufacturing apparatus to manufacture, over one or more additive manufacturing steps, the product according to the surface configuration specified in the electronic file.
