Needed a nozzle with a narrower tip for my Shop Vac so I designed this in OnShape as a learning exercise. I ended up doing a bunch of different sizes and lengths. All of them should fit on a standard fitting which measures just under 60mm OD. I've added a fitting for use with smaller hoses. I recommend printing it almost solid for strength. I used 4 walls in PLA and so far it is holding up well. Had some adhesion issues so I added interior and exterior brim and raised the first layer and bed temperature by 5 degrees and all went well.
