Vacuum crevice/suction attachment

thingiverse

This is a custom hose/wand attachment for a Meile vacuum cleaner. You can likely use it for other makes and models with a bit of resizing. It has a small-diameter angled tip that's great for getting into tiny crevices. I've also used it vacuum seal items in resealable plastic bags. Place the tip of the attachment just inside the bag past the seal on one edge. Close the seal onto the tip. Vacuum out as much air as possible, then quickly remove the tip and press the last bit of the seal closed.
