Bench Power Supply

Here is my bench power supply made from some spare components and a 3D printed case. The power supply provides a useful regulated DC voltage, adjustable from about 1V to 16V DC at 4.5A. The power supply is based on the XLSEMI XL4016 Step Down Power Module.

The power supply integrates a 4 digits voltage and current display. The output is an adjustable constant voltage and/or constant current supply. Assembly and circuit information is included in a Word document.

Here is my 3D printed solution case for the power supply. The top part of the case secures all the internal components into place. There is also a separate 3D printed front panel with printed text to give it a clean finish. The internal power pack is held in-place by a 3D printed clamp. The final 3D printed part is a case cover, held in-place by 5 screws from underneath.

To make the print result more interesting, for the front panel, I do a filament colour swap near the end so that the raised text is printed in
