Filament Storagebox Clamp

Found this box in the local DIY Hardware store (german OBI), but there were no sealed boxes, so I took these aftermarket window seals and added them inside the lid. The box has already brackets to fix the lid, but with the window seal it needed more,
so I created additional brackets.
It's probably not 100% sealed, but I can hear the air squeeking out when pressing the lid down.
At least ten spools can fit in there, probably more when properly placed.

Update 2019:
After a year of using this customized storage box there is still no crackling while printing with the older filaments stored in this box, so it worked and did not get hydrated too much.

Then got a new storage box so needed couple more clamps, I decided to recreate it in FreeCAD, that's the last STL file added.
It has rounded corners and chamfers all around, no post processing needed at all.

Size: 60x31x8mm
