Before you commit to printing the whole model. It is recommended that you print the much smaller Print_first_to_test_blade_fitment.stl first in order to ensure that you have the correct settings in your slicer. This will also give you practice installing the blade. A correctly printed object should have tight blade fit and it should a struggle to install. If it is too loose it could be a danger to the user. As always, use common sense when installing the blade. A small pair of needled nose pliers is recommended.
The author remixed this model.
In the original design the blade would not sit flush thus allowing the paper to get caught underneath the blade. This version was modified to include a 1mm depth cut to accept a recessed #11 Blade. Apparently the original was removed.
