120mm PC Fan to 2.5in Segment Hose Adapter

I wanted to use this segmented hose with a 120mm PC fan, as I have many cheap 120mm PC fans I've collected over the years, so I designed this adapter.

Print Settings:

1. Vase Mode
2. 0.8mm - 1mm External Perimeters 
3. 0.15mm layer height for the vase (1.7mm → Top)
4. 0.3mm layer height for the base/bottom (0 → 1.7mm)
5. 6 Solid Bottom Layers (12 if using purely 0.15mm layer height)

I printed mine in PETG, but it would probably also work in other materials. The flexibility of PETG works well in this application. 

Please let me know if this works well for you or helps you put together a cool fan or fume extractor.
