Basic tool to test the strength of the samples. The tool was designed for 80x10x4mm test samples (standard for 3 point bend). With this tool you can only check the point at which the test sample breaks (weight at brake), It's not prepared to measure the deformation. Thanks to this simplicity, the toll does not require any additional assembly features (bolts, glue etc.)

It's a great print for showing  people that are not familiar/new to with  material/ structural strength of the 3d printed (and more) parts. I used it for a workshop with kids where we tested some different materials and print orientations.
