Tips:

1 Due to differences in materials and printer types, print quality and tolerances may vary. After printing, if you find that the fit is too loose or too tight, you can scale parts of the model as needed.

2 If some connections are loose or fit too tightly, you can use some glue to secure them, or sand down the corresponding parts.

3 Due to variations in materials and printers, perfect compatibility with all models and materials cannot be guaranteed. We appreciate your understanding.
