Adjustable Stanley blade holder for a film slitting machine

I have some converting jobs which I run on one of my die cutting machines and needed an adjustable holder to hold a Stanley blade. Worked quite well.
Pause at Z height 8.5mm to insert the M6 nut on the actual blade holder part.
The slot for the blade it's self might need supports but watch out for supports in the area where the M6 nut might go.
I printed mine without supports and although a little untidy got away with it for the slot.
Tap the through hole M6 all the way through, use a locknu
