Here is another video of it curled on the end of the tail.
Also it can’t be temp. My nozzle is set to 180 C, which is 20 below this filaments recommendation. The bed is at 50.
180 is too low. In my tests, I had to use higher temperatures but add more ventilation as the SM default cooling is flawed (as Brent suggested).
/Edit to clarify since I’m going against other suggestions, I got better results using higher temp AND added cooling, than simply try to go for lower temps.
Also, you can try to scale the object up or adding a second object.
Your test object has curling hell-inducing features, so this might help you:

Did you activate the part cooling fan?
Your surface is too small to get proper cool.

Cura has the fan on 100 all the time by default I think. I did notice it print a lot better when I put a table fan next to the printer pointed directly at the print.
This is definitely part cooling related… if you put two of these next to each other a little bit apart I can almost guarantee you will get better results… the filament does not cool sufficiently before the nozzle is back at that location and it makes it curl… f’s up the rest of the print. Putting two a little bit apart will give the filament time to cool. The cooling mod was mentioned earlier and I can say it really works well.
Try taking the build plate temp down to 50 (i usually do 60 for first layer) and after putting down the first layers try to get some fresh air to allow more part cooling. I had a pc fan blowing into the enclosure for a while before I did the fan mod.
