Printed with PETG and working with my Dyson DC44 animal. It was a bit loose, I considered resizing it, but realize it was smarter to just make it thicker with tape. Now it's very snug with just like 3 layers of painters tape so easy to remove. I also covered the holes near the attachment as they seem to make the suction weaker.

Exactly what I was looking for, and fits the vacuum perfect. Thanks for making this
