Hello, I'm a beginner when it comes to creating 3D models. I'm trying to add more designs to the models collection: https://www.thingiverse.com/thing:1258505. I need assistance with adding: - Norse boats. For the Drakkar, I took inspiration from this model https://www.thingiverse.com/thing:204633 and converted it using MS 3D Builder. However, I'm struggling to enhance the 3D mesh for printing at a small scale. Can you help me improve these designs? Thanks
