It works, but the head sits a bit too low in the adapter. If the bottom were solid and a ring of material extended above the neck slot, it would raise the head up a bit. As it is, the Titan Master's feet hit Nightbeat's back. Raising the whole thing up two millimeters would work wonders.
Also, and this isn't the design's fault, acrylic might be too fragile for this (the back "panel" of mine has snapped off).
