Took @Wolfie3D_373632's fusion360 file and made changes to accomidate a 63mm (2.5in) hose. This is a straight 63mm no taper, with a 4mm wall thickness for added strength.
Thankfully he included sketches so this novice F360 user could manage the changes.

I used 3mm foam tape to seal the edges against the back panel, three M3x10mm screws and one M3X12mm. With a little force you can cut threads into the unused holes on the back panel which is what I did, just dont overtighten as with the foam it can crack the print (I used PLA). The 12mm screw was used in place of the factory screw that was removed.
