<p>Adjustable (voltage limit, current limit) PSU DC/DC converter PSU power supply and display box</p> <p>This is a case for a XL4016 based buck or boost converter that accommodates wheels to set the voltage and current as well as a spot for a dsn-vc288 panel voltage / ammeter</p> <p>At the back there is space for two XT60E-M (the panel mount version of XT60) connectors for input and output.</p> <p>You can add a fan to the top if you find you need one, there are air out/inlets on the top and the sides.</p> <p>UPDATE 8.8.2020: After printing i found that the knobs that slide over the 3296 Trimmer Potentiometers do not work very well at all. This is why i would suggest that you replace the ones on the original board with long knob versions of the same value and precision Potentiometer. It will be much easier to attach a knob to it, or you can just tilt the entire Potentiometer forwards, attaching it with super glue or so. I will be uploading a second version of the shell for that.</p> <p>Since the bridge for the display was pretty long i added built in supports. They should make this print considerably easier even with materials like PETG or ABS or if you otherwise print a material relatively hot.</p> <p>V5 is the old version, V6 is for the new tilted 3296s. (the photo shows V4, basically V5, but with some missing features, it still has the old style knob opening, but the knobs are not attached, the gray rendering is V6)</p> <h3>Print instructions</h3><h3>Category: Electronics Summary</h3> <p>Adjustable (voltage limit, current limit) PSU DC/DC converter PSU power supply and display box</p> <p>This is a case for a XL4016 based buck or boost converter that accommodates wheels to set the voltage and current as well as a spot for a dsn-vc288 panel voltage / ammeter</p> <p>At the back there is space for two XT60E-M (the panel mount version of XT60) connectors for input and output.</p> <p>You can add a fan to the top if you find you need one, there are air out/inlets on the top and the sides.</p> <p>UPDATE 8.8.2020: After printing i found that the knobs that slide over the 3296 Trimmer Potentiometers do not work very well at all.
