Chefs Choice 615 Blade Retainer

I'm not entirely convinced this qualifies as a remix, as it's more like a complete rebuild. I couldn't successfully import the source files into TinkerCad, so I had to start from scratch. Still, if not for the original design, this project would have been much harder. The reason behind this remix is that both the original part and its 3D-printed replacement failed in the same way, prompting me to create a stronger version. This new design should offer several improvements: It features a reinforced back where the bolt attaches to the slicer, which was the weak point of the original. A different screw thread (M20x1.5) has been incorporated since it's easier to work with in TinkerCad. The thread tolerances have been slightly loosened for less fiddling during assembly. It can be printed without any support material. The edges of the part that protrudes from the nut have been rounded to make handling easier when tightening or loosening the threads. Lastly, I've adjusted the positioning holes as the added material made it difficult to align with the originals (at least according to my measurements). Keep in mind that the placement of the pins might vary between machines.
