ATX-Power-Supply for STEM Version 2

### ATX-Power-Supply for STEM Version 2 ### This power supply design has undergone significant improvements since its first version. I've used it extensively with my students to conduct various experiments. You can view the original design at https://www.thingiverse.com/thing:3876829. The main body of this updated version features a more stable build, which slightly increases printing time. However, this upgrade also allows me to utilize the 3.3 volts offered by an ATX power supply, providing additional options for experiments. A USB interface has been added to enhance connectivity and functionality. Users can now design their own front panels according to their preferences, offering endless possibilities. I didn't create the front panel with ten USB ports myself, but it may be useful to someone. The back of the design has been optimized in terms of dimensions for improved usability. A photo of the wiring is included, and I've taken extra precautions by wrapping the step-down converter in shrink tubing to prevent electrical contact issues. <b>Important Note:</b> I do not guarantee the accuracy of the circuits (please refer to the accompanying pdf!). Anyone working with electrical equipment should be well-versed in its operation. If you're unsure, it's best to consult a specialist before proceeding.
