Hello, I'm a newbie in 3D model creation. I try to add more models to the models group: https://www.thingiverse.com/thing:1258505 I need to add : The norse boats. For the Drakkar, I toke inspiration myself from this model https://www.thingiverse.com/thing:204633 and I converted with MS 3D builder. I'm not able to improve the 3D mesh to print in small scale. Help me to improve these models. Thank you
