Here are mine.
BK2 Box for the stock sheath, and a drop leg carry system, as well as some short and sweet mods to the sheath itself.
Floppy belt loop got yer sheath down? Perk it up with an easy fix!
I sewed a straight line directly across under the rivet that holds the retention strap in, which was also the same size as credit card sized stuff. It holds a fresnel lens, EZ Lap Diamond Card, and a plastic card with some basic survival info on it. Then covered with inner tube to hold in the stuff.
Allen wrench storage is two one inch nylon spacers from Lowes in the indicated sizes, with notches to match up and hold them in place inbetween the loop plate and the sheath proper.
BK2 Box was 3D modeled, then printed by shapeways.com in their white strong flexible material, then painted.
Drop leg attachment was made using a two inch buckle from wal-mart, a two inch wide piece of nylon webbing, four snaps, a two inch aluminum screw post, a half inch aluminum screw post with open back, a one and one quarter inch stainless steel screw. Buckle had the plastic bar cut off, holes drilled to take the aluminum screw posts, and then those were inserted through the existing belt loop of the knife.
Not shown in the picture is that the leg strap has since been replaced with an elastic webbing band, which works much, much better.
