Nickel strip box

I have created two boxes for the nickel stips that i use for battery welding, with the width of 27mm and 10mm (i actualy use one 8mm strip). It allows me to keep the strips untangled and straight. For cutting, the strip is extracted like a measuring tape and the excess can be pushed back in the box. It requires one bolt M6x30mm, one bolt M6x20mm and two nuts (i had wingnuts that works better in this case). The smaller box can be made more than one, for strips of different sizes , and stacked with a longer bolt.
