When you need to hook a vacuum cleaner up to some 32mm pvc piping, for things such as a DIY dust extractor, vacuum table, etc. Then you're going to want a way to make that vacuum hose fit nice and snug.
Enter this adaptor. It is tapered to fit most vacuums. It's also tapered to ensure a tight fit into a pipe coupler for 32mm pvc pipes. We tested it with a 32mm compatible ball valve. It worked a treat.
Not a difficult thing to print. There's a little bit of overhang, but you can easily sand it, and it'll look alright. Just use a brim to ensure platform adhesion. Use supports if you really want, but this thing should print happily at 0.2mm res.
