Those items you printed are very tall and skinny. What you see towards the top is that the layers are not cooling before the hot end goes back over it and adds another layer. If you watch you will even see that the print looks "rubbery" while it is doing this. One way that folks fix this is adding a fan pointed at the print. Another way is to print two or three of those at once so that there is time for the print to cool before adding the next layer.
