Make: 2015 3D Printer Shoot Out Test Models

Make Magazine's third annual 3D Printing Shootout was conducted using these files, created by Andreas Bastian to benchmark performance of desktop 3D printers. You can read all 26 machine reviews in Make:'s Annual Guide to 3D Printing 2015 (Volume 42).

These test geometries are designed to evaluate specific performance characteristics and motion systems in common low-cost FDM/FFF machines. Traditionally, layer height has been used as a proxy for resolution or quality, but it is a bit of an oversimplification of what is often termed "print quality".
