Double Edge (DE) Razor Blade Storage Box

This is a storage box for double edge (DE) razor blades. I measured various card and plastic 5 blade boxes and got a maximum size for each. (I only had Derby and Feather plastic boxes to measure).

Each slot is 54mm wide, 100mm high, 32mm deep minus 2mm ridges in the bottom.

There's an extra space at the front of the box for other items. I chose not to make the slots wide enough for the oversized Wilkinson sword blades as they aren't something I will be using in future anyway.
