Isn't it annoying when you can't find the accessory tools that attach to your vacuum cleaner? You know you put them in a box, and put the box in a closet, but you just don't remember where they are. I recently bought a Shark Rocket vacuum and I really like it because it takes up very little space in my tiny workroom. But there was no way to keep the accessories with the vacuum so they would not get lost. So I designed a clip to keep them attached to the main tube/wand. I printed three of them in silver PLA. The smaller diameter side of the clip attaches to the main tube/wand, and the larger diameter side clips onto the concave area on each accessory tool. I sliced this using Slic3r, and I used .6mm extrusion width with minimum perimeters = 5, and zero infill. This forced Slic3r to use extra perimeters to fill in the area in the center where the large and small C-shapes meet. This makes for a smoother print with less stringing than using other infill patterns.
