The author remixed this model.
I enlarged the pegs that support the knives, and added a lip to the pegs as well to keep them from sliding off. I made a 3 peg and 4 peg version, since the Stitch is so larger, the 4 peg wasn't giving me the clearance I wanted. I also uploaded two lengths of pegs, if you need longer, you can make more in Tinkercad. I used 2.75mm x 2.75mm, but if you go too long it may tip without a larger base.
