I bought an ancient Kirby vacuum cleaner for cheap (you know, the ones that can survive a direct nuclear strike and keep working). Problem is it came with no hoses. . My idea was to print an adapter that would allow me to use a surplus hose from a dead vacuum instead. . I haven't yet tried to print this thing, so some adjustment may still be necessary.You'll probably want to download the .scad file and tweak the first two sizes to fit your replacement hose.
