Filament Cutter TWIN blade for MMU

I didn't find any cutter who cuts filament in arrow shape, which is best if you have MMU3 unit. cutting with cutters is a pain… cutting wrong and filament will stuck when inserting. This remix cuts on both sides at 45 degrees, so end result is nice arrow shaped tip. I used 18mm blades with narrow (double) segments, like this: https://www.aliexpress.com/item/32731131573.html - this is just an example, i'm sure there are cheaper out there… Also base part is changed in a way so that indentation (chamfer) for filament inserting is only on one side, since this is important. For a perfect arrow cut don't snap quickly all the way, but press gently so that blades grab filament and it centers on both blades, only then fully press/cut. Also make sure that both blades are equally inserted in top part.
