This model is easily buildable. You may need to sand a little bit to get the pins to fit but they slide together really nicely. You will need glue to attach the end caps into the pins. Hot glue works fine. The short pins go into the middle and the long pins go onto the ends of the bars for the hats to hang on. No supports or anything just download and print!
