The Structure of the Kuiper Belt: Size Distribution and Radial Extent, Brett Gladman et. al.
Bottom of page 1065: The disk mass in the observed region out to ≈ 60 AU is ≈ 0.1 Mearth (6e23 kg), only weakly dependent on the roll-over size and radial distribution.
The Kuiper starts at approximately 30 AU and is constrained by observability. A 1.5 g/m2, 50 AU Dyson shell ( 7.46E9 km, 7e20 km2 ) uses 1e24 kg of ice and other materials; that is cut in half if the shell uses front-side IR filtering.
