The fact the "dust shroud" is now open on the OF 1010 R is more reason for one of us to design and 3D print a similar solution for the 1400. The design on that unit is really bad. Of course, the angle of suction on the new 1010 has got to be a big part of the "open solution" but still one of us can figure this out for the 1400, right? I really dislike the 1400's approach to this.
