Funnel on bottle

I have made funnels with different bottle mouth diameters, which will be very beneficial to the recycling of resin,

At present, the diameter of the matching bottle mouth is 60 50 40 34mm. Another funnel with other diameters is hidden in the folder in my computer. When I find it, I will send it out

When printing, you only need to paste the bottom, and you don't need support
