An adapter I made to use my Kirby attachments with my ShopVac which has a 1-3/4" hose.
Now I can use the duster attachment to clean the car!
I used 0% infill and 6 shells so that the printer would just keep making circles and the print would be fast and strong. Check the model before printing to be sure you don't have a gap between the walls. If you do, you may want to turn the infill on.
