Hi Folks,
Just got into 3D printing on an regular Ender 3. I do whimsical stuff and use slow-running slot cars with the my trans. In the video below, these were my test prints (low quality) however, they turned out well enough for me. The tender is a version of my styrene tender from my Porter project OGR published in Run 227.

Learning more and more every day. Frustrating at times, too!
Take care, Joe.
