Flip top R8 collect holder wrack

[PixMan]

I really like the idea of a rack like that. Mine is one my dad made, and he later fabricated a curved, open-ended polycarbonate shield for it. My only issue is that its not big enough to hold the "extra" tools, namely my R8 and straight shank drill chucks. Perhaps I could lose the couple of collets that have a duplicate, I just have a have time deciding which one I like better.
