I love the Shishi-odoshi style fountain, but, wanted something a little more authentic. I took one of the bamboo pipes from 'Bamboo Zen Vase' I cut op...en the end of the pipe, and then added a little to it to close it off and add some weight. As i was remixing it, I made a thin wall, but it did not seem to work that well so I made it thicker. This one works well for me with the water flow slower. I decided to add both so you can choose which you want to use.
I did a 20% infill and that seem to be the perfect weight.
