Popo Premature Prop Ejection Preventer

Every once in a while I tag the top of my popo motors either on the underside of something, the side of a gate/obstacle, or have a prop shoot off into the sky while in turtle mode after the popo pin gets activated inadvertendly.

Now I just have these printed in TPU and pop them on top to prevent that from happening - so still no bolts required, and no weird prop ejections.
