My son made a pipe stand for me with his 3D printer. Nothing fancy, but it serves the purpose. Now, he's going to make a larger one because this one, as you can see in the pics, is a little tight. I'll use this one for straight stem pipes. I also suggested to extend the center column so the stand can be picked up while the pipes are resting on it. I'll post an update of the new version when I have it.
