Funnel with airtube for faster fillin

I made this funnel to make a faster filling. On the photos you can see the same funnel, once scaled up to 140 %.

100%=15.5 mm diameter on the infill
140%=21,2 mm diameter on the infill and 26 mm after 30 mm

Version 2:
Because you liked it, i made a better version 2 with airtube inside and a longer tail end. Perhapes someone can post a made.

Give me a like if you find it useful.
