Speaker stand for Kef e305 surround speaker

thingiverse

I created this speaker stand to elevate two of my surround speakers to ear level. It was created in Cinema 4D. There is one non-manifold edge that I can't seem to resolve. However, it printed fine using Simplify 3D to slice it. I printed it with 4 perimeters, 3 bottom layers, 6 top layers, and 15% infill with a .02 mm layer height. It's supporting the speaker 5.3 lb with no problems.
