Note: If this model receives enough attention, I might design a remote-controlled version in the future.

 

Printing notes:

  • Every 3D printer behaves differently.
  • The tolerances in this model are about 0.02 mm.
  • If some parts do not fit perfectly, gently scaling the small pieces will solve the issue.

This model is ideal for collectors, hobbyists, and naval enthusiasts who want an accurate representation of the USS 688i submarine in a compact scale.
