I created this model that perfectly fits the bottom profile of the Neumi BS5 Bookshelf Speaker. It is angled upwards at 13 degrees for a great on-axis nearfield listening experience. These fit the Neumi speaker profile best when you use the included rubber pads from Neumi on the bottom of the speaker and place some ~4mm thick felt, rubber, or dense foam pads on the back edge of the riser as shown in the second photo.
