The model's 1:1 ratio and internal architecture are finely tuned, allowing every component to be easily visible from the outside - including the removable barrel, adjustable gun stock, detachable secondary mirror, removable gun, and other assembly gaps that have been carefully left unsealed. To accommodate most 3D printers, you can use magic to shrink the model's surface by a mere 0.2mm. Secure it with set screws and glue for added stability. Prior to assembly, verification has not yet taken place; however, comprehensive instructions will be provided at a later time to ensure seamless construction. The printing parameters are as follows: Layer thickness: 0.2mm Wall thickness: 0.8mm Filling rate: 20% Material usage: 580 grams Estimated print time: 60 hours
