Filament Cutter 45deg with a new top that takes M3 nuts

I made a new top button a bit taller and put in slots for M3 nuts.  Adding M3 screws (30mm) with nuts reduces plastic fatigue. Insert the nut with one of the nut's chamfered edges pointing out. I Remixed the body also with deeper channels for the button, this helps a little with longer springs, but it's not necessary.  The top button should be a direct replacement for the original. Also note the slot for the nut is intentionally a tight fit so your printer should calibrated especially horizontal hole expansion.
