Slatted cover for the external vent of a clothes drier
Description
Two days ago, I noticed that the outside vent for my clothes drier was shattered, I have no idea what by. There was a hole in the wall that could let in rain, or be nested in by a bird, whose eggs would then get nicely cooked next time I used the machine (shame!) I stuffed some rag into the hole to keep the birds out, and decided that it would be fun to design one. The hole in the wall is 146mm across, so I made the cover 150mm internal, and 156 external, with walls that were 3mm thick. I sloped the upper and lower walls downwards, to shed moisture better, and the inside of the side walls I made taller than the outside to discourage rain ingress. The slats are 30mm long, overlapping by 8.5mm, and with a gap of 5mm between them. The bottom slat overlaps the bottom of the frame by 8mm. (approximate measurements). And here it is. You can print it as I did, on its side, with supports for the upper surface. This technique gives you the print layers at 90 degrees to the long axis of the slats, making them stronger,. Alternatively, you could print it with its top on the bed, with supports for the upper surface. This produces slats with all the layers parallel to their long axis which is a weaker build. As luck would have it, the weaker build is marginally faster to print. To be fair, this is not a high stress item - probably either technique would be fine.
