PCB-based weighing scale

I wanted to design a PCB where I can test a few things. I wanted to see if I can use the traces as strain gauges to detect bending. My original concept was not working, but I could still use the PCB for the intended purpose with a little workaround. I put some funny shapes and curvatures on the PCB and all of them were machined out nicely. No burrs, and no bad surfaces. The traces were also nicely etched and the holes well drilled perfectly as well. I chose the 1 mm thick PCB to have a little additional flexibility. The board flexes nicely while still being strong enough. The order was fulfilled rapidly and my package arrived to my address before the predicted delivery date. Everything was packed well and securely.
