I have a black lab and when I was looking for a spinner design to put on the extruder motor post for my printer I went looking for a nice Labrador design and found one produced by dogbrand. I also copied the base from the "Hurricane Kick spinner" by kapakai. I took both files into Tinkercad and used the post to hollow out a receiver hole in the lab. I tried two different height posts. The shorter post is about 5 mm shorter and just clears the boden tube attachment. You may need to ream out the hole in the post a bit to get it to fit on the extruder depending on the filament and resolution you use.

The lab needs supports from the print bed.
