Creative Tools has just released a new 3D printer benchmarking and calibration tool called the #3DBenchy. It is a small tugboat which can easily be used to check your 3D printers calibration and benchmark it again other 3d printers. Best of all, it's a fun little toy to play with when done with your tests. The STL file is free to download and all of the measurements are provided for you to benchmark against.
