PEX Guide Plug

I need to run PEX tubing through some old construction and wanted a cap that could protect from getting debris in the tubing and act as a guide to keep from getting stuck in tight spots. Here are both 1/2" and 3/4" sizes. I have included .stl files that can be printed standing up with no supports. If you have any doubts about bed adhesion a brim will help. 

I also included a .3mf file that has the plugs split and includes alignment pins. This can be printed lying down without supports. I used a brim for the alignment pins. This orientation will make a stronger structure that is much less likely to break with lateral stress. This is probably not necessary but hey, why not overbuild something when there's a chance to do so. (NOTE: The holes for the alignment pins don't show up in the 3D preview here but they really are there and will be visible when you open the .3mf file in PrusaSlicer.)
