This guide works great with the side mount M3D Spool holder.For the best results, this should be made with the long end of the hanger bracket flat on the bed, as shown in the last photo of the gallery. When printed this way, the funnel requires the least amount of clean up. I printed using Medium Resolution and Full Fill. It will print with the bracket on its side, but the funnel doesn't come out as nicely formed as the other way.
