Prusa-I3 Clone strentghening bar

This is a strengthening bar for front Y-axis bracket (7mm thickness) on a Prusa-I3 Clone.
After printing many pieces I suddenly had one failed print. Turns out the front bracket for the Y-axis was flexing which in turn allowed the tooth belt to slip. I have installed a metal angle bracket and this strengthening bar. But you might just want to try this first and then add a metal piece if needed.
