My wife ordered a storage bag for her christmas tree and was worried about the end poking a hole in it. So i designed these protectors to cap off the sharp connector ends of the tree.

It has a little ridge inside to place pressure on the pipe to hold it onto the tree, if it doesnt seem like enough i also have a groove around the outside for a zip tie or to place rubber bands on or something

You may need to resize the models to use your specific tree, the pipe I have designed them for are: 1.26in for the pointed pipe, and 0.8 for the flat ended one.
