Form for slicing Thomas English Muffins

See UPDATE below:

So sometimes I want to have a clean cut of a Thomas English Muffin to put in the toaster
So with this form you slide the muffin down from the top, and use a serrated knife to slice the muffin in half.

There is room at the bottom of the form for the knife to completely cut the muffin and then drop down to an empty space where you can slide the knife out without impacting the muffin. 
 

The empty space at the bottom of the form is 26 mm deep for the knife, and the space for the muffin is 113 mm high and is 30 mm thick

Its about a 13 hr print

UPDATE: I was asked to make an updated file that would slice the muffin with a larger slice for the muffin top, and a smaller slice for the muffin bottom.
While most muffins are very near the same weight, the top half, and bottom half, can vary by many grams, due to their inconsistent top half shape.

So the picture of the updated green slicer shows by placing the top half of the muffin near to the slicer handle, the slices will be more evenly weighted. See also the pictures of the top and bottom slices on a scale.

Enjoy !
