Boxcutter blade bin

Do you use boxcutters in your workshop, home or at work? What do you do with the spent bladeparts, you break off when they become dull? I've been dumping them in empty soda cans because they are around.

This has annoyed me. So i've designed a bin for the discarded blades. I've slanted the upper edge to facilitate breaking the blades off.

It can handle blades up to a width of 18 mm (0.71").

Its dimensions are 23 mm x 64 mm x 47 mm (0,9" x 2,5" 1,9")
