This is my own model. Please do not confuse it with other models, as only the knife handle type is the same, and the other blades and components are all my original creations. When assembling, you need to first place the largest blade printed face down on the table, and then place the smaller blades in the same direction. Starting from the smallest blade, you need to manually remove the support structures. In addition, it also includes test files, so you can try out the settings you are using at any time.
