在MakeOrderButtonsForStickers函数中返回贴纸，如下所示：

def MakeOrderButtonsForStickers(self, get_mat_ID, mat_distance, x_mat_distance):

    get_mat_name = get_NameOfMaterial(get_mat_ID)
    ItembyCategoryCheckBox = ctk.CTkCheckBox(self.StickersFrame, text=get_mat_name,
                                             command=lambda: self.Add_To_Order_Materials(get_mat_ID, get_mat_name),
                                             fg_color="#a881af", variable=self.ChoosingVariable,
                                             onvalue="1", offvalue="0", width=150, height=40,
                                             text_color='black', font=("arial bold", 20),
                                             border_width=4,
                                             border_color='black')
    ItembyCategoryCheckBox.place(x=x_mat_distance, y=mat_distance)
    return ItembyCategoryCheckBox

然后你可以创建一个类的成员变量，比如sticker_checkboxes，然后在for-loop中使用enumerate按索引赋值。

...
        for idx, stickers_item in enumerate(Stickers_Categories_ID3):
            get_mat_ID_str = str(stickers_item)
            get_mat_ID = get_mat_ID_str[1:-2]
            int(get_mat_ID)
            if mat_distance >= 150:
                x_mat_distance = x_mat_distance + 200
                mat_distance = 10
            
            self.sticker_checkboxes[idx] = self.MakeOrderButtonsForStickers(get_mat_ID, mat_distance, x_mat_distance)
            j = j + 1
            mat_distance = mat_distance + 60

现在，您有了一个复选框列表，按创建它们的顺序排列。您也可以将sticker_checkboxes作为dict，并在get_mat_ID上建立索引，这取决于您。

因为你已经为所有 checked 的项目使用了相同的示例变量（self.Material_Order_Text，self.Material_quantity_text和self.Material_price_text），所以它们将引用最后一个检查的项目。
我建议使用字典来存储那些使用 Mat_ID 作为键创建的标签，然后您可以使用 Mat_ID 轻松访问它们。
下面是修改后的Add_To_Order_Materials()：

def Add_To_Order_Materials(self, Mat_ID, mat_name):
    print(self.ChoosingVariable.get())
    Mat_Price = get_PriceOfMaterial(Mat_ID)
    if self.ChoosingVariable.get() == 1:
        if mat_name != self.Name_Order_Counter:
            self.Item_Order_Counter = 1
            self.Item_Order_Distance = self.Item_Order_Distance + 30
            self.Name_Order_Counter = mat_name
            self.Material_Order_Text = ctk.CTkLabel(self.ordertotalframe, text=mat_name, font=("arial bold", 20),
                                                text_color='black')
            self.Material_Order_Text.place(x=55, y=self.Item_Order_Distance)
            self.Material_quantity_text = ctk.CTkLabel(self.ordertotalframe, text=(str(self.Item_Order_Counter) + "x"),
                                                   font=("arial bold", 20), text_color='black')
            self.Material_quantity_text.place(x=210, y=self.Item_Order_Distance)
            self.Material_price_text = ctk.CTkLabel(self.ordertotalframe, text=(str(Mat_Price) + " €"),
                                                font=("arial bold", 20), text_color='black')
            self.Material_price_text.place(x=300, y=self.Item_Order_Distance)
            self.Item_Order_Counter = self.Item_Order_Counter + 1
            self.Order_Total_price = self.Order_Total_price + Mat_Price
            self.Order_Total_price_Label.configure(text=(str(self.Order_Total_price) + " €"))
            self.Material_Order_Text.place()

            # ************************************************************ 
            # use a dictionary self.order_item_labels to store the labels
            # note that self.order_item_labels should be initialized
            #   elsewhere, for example inside __init__()
            self.order_item_labels[Mat_ID] = (self.Material_Order_Text, self.Material_quantity_text, self.Material_price_text)

        else:
            self.Material_quantity_text.configure(text=(str(self.Item_Order_Counter) + "x"))
            self.Material_Order_Text.configure(text=mat_name)
            self.Item_Order_Counter = self.Item_Order_Counter + 1
            self.Order_Total_price = self.Order_Total_price + Mat_Price
            self.Order_Total_price_Label.configure(text=(str(self.Order_Total_price) + " €"))
    else:
        self.Name_Order_Counter = ""
        # clear removed order item
        for lbl in self.order_item_labels[Mat_ID]:
            lbl.place_forget()
        # remove the item from order list
        self.order_item_labels.pop(Mat_ID, None)
        # populate order list
        for i, labels in enumerate(self.order_item_labels.values(), 1):
            y = i * 30
            labels[0].place(x=55, y=y)
            labels[1].place(x=210, y=y)
            labels[2].place(x=300, y=y)

        self.Item_Order_Distance = self.Item_Order_Distance - 30
        self.Order_Total_price = self.Order_Total_price - Mat_Price
        self.Order_Total_price_Label.configure(text=(str(round(self.Order_Total_price, 2)) + " €"))
