There were a couple of pieces that were difficult to print In this set if the bed is not exactly level, as the top is wider and heavier than the majority of the model and could therefore overbalance or knock the model when printing.
There are a couple of things that you can try first if you haven’t already to make sure it’s not the printer itself. the first is to increase your retraction settings and slow the print down to try to prevent it knocking the part as it travels. the second would be to, when you re-slice it, to re-orient it on the bed as well at 45 degrees to make sure it isn’t a slight bed leveling issue.
