This holder works well when printed in PLA+ or PETG, with some light supports on the hole where the vacuum attachment clips into the holder. There are two screw holes to mount the holder to your wall, although you can use double sided tape if you don't want to drill holes in your walls. The holder is slim enough to fit behind a hanging v8 model vacuum but far enough from the wall to accommodate most of the larger cleaning heads
