About this 3D model

An elbow for a 120mm fan. Screw holes where they were on my standard 120mm fan. Outside diameter of the hole is 70mm This is my very first design and was made for my own use. I decided to share this in case others can't make one. I'm not professional designer. This elbow/fan part can use an update but works well. Some stringing on the top but otherwise solid. Recommend using supports if your printer has any challenges with overhangs. Boost Me Please boost my first design its not much, but it works!
