Needed a spike for holding down the hose in the garden. Can't just use a piece of bent wire can I? The x6.stl is spaced so using ditto on sailfish will double the output producing 12 instead of 6. (Posted version is reenforced from the ones shown in the picture but I recomend an aceton vapor bath before using them to solidify the outside.)
