Updated and improved Speed Funnel 3 is now available for download on my page. This file will no longer be updated. 

You can adjust these, just keep in mind the tabs on the side are about 5mm each before manipulation. 

You can switch this to PETG or anything else in slicer, it doesn't need supports or any changes for the material to change. You could print it out of TPU even, whatever works for you. 

If the seam is bothering you, set the seams to “random” and it will go away. 

Happy Printing ! And THANK YOU for all the boosts and likes. I never expected this print to be so popular, but I am glad  you all like it.
