Again the box in the picture is not completely glued yet, so there are gaps. Your box will not have these.
The box is done and there is a place for all the blades. The long blades (Housing, fine point, fabric etc) go in the holes with the lower level cut out so that they hang down. The tips used with the interchangeable housing sit in the other holes and can still be grabbed easily without the danger of cutting yourself.

Ingenious!
Great job with this. There are several blade holders out there but yours is easy to make and works just fine. Thank you for sharing.
