This design was intended to be an option for a blade holder that takes up very little real estate on the pegboard and very little filament. There's a slight tilt on the mount to keep the blades from leaning over as the printer shakes and falling out. It looks best if it's printed upright as is in the profile. If you don't care about looks you can rotate it on it's side and it prints faster.
