Saw Stop Dado Blade Holder

I've been setting up my new (and first) woodworking shop and trying to get organized.  I'm trying to use the limited space wisely and building a table saw accessory cabinet to fit under the extension table of my Saw Stop PCS.  I made the bottom drawer tall enough to hold saw blades.  This makes for a handy place to store my dado set.  The set comes in a nice case, but it is too tall to stand up inside the drawer and I didn't want to have it laying down taking up all the space, not to mention having to dig it out after piling other things on top of it.  I wanted quick, convenient access to the dado set, so I designed this holder.  It includes 1/8" spacers to ensure the carbide tips of the blades can't contact each other.  I also added a wing nut to keep the blades in place so they don't rattle around when opening and closing the drawers.  (One of the photos also shows my spare brake holder, which I will upload shortly.)
