This is a test model for making threaded parts in Bambu Studio. It includes 3D printed bolts, nuts, and parts that can be combined with standard metal screws and nuts. You can check thread pitch, size, clearance, and fitting before making your own parts. The model is useful for learning how to adjust screw settings and for testing practical threaded designs. Printed with SUNLU PLA+ 2.0. Please watch my YouTube video for the full explanation and setting guide.
