Power supply case

<p>Powersupply case for laboratory powersupply made of "china" parts. In my case its 0-32V 5A with bluetooth support (android app).</p> <p>There is stl Powersuppply_case_complete_do_not_print.stl - it is only for full overview of the case - do not print this file ;-)</p> <p>I printed it with some unbranded brown PLA and it came out like "vintage" box. So i call it vintage powerbox, maybe the rounded corners did this vintage look :-)</p> <h3>Print instructions</h3><h3>Category: Electronics Summary</h3> <p>Powersupply case for laboratory powersupply made of "china" parts.

The shell part warps a lot but it is not a problem at all. You should try to print upside down with lot of supports maybe with better result.</p> <p>To mount components use some spare screws - holes are 3mm diameter.</p> <h3> How I Designed This</h3> <p>Measured components and tinkered in tinkercad</p> <p><a href="https://www.tinkercad.com/things/e7ovzq23rTa">https://www.tinkercad.com/things/e7ovzq23rTa</a></p> <h3> Custom Section</h3> <p><strong>Electronics parts</strong></p> <p>List of electronic components to build same power supply.

It works with this android app. Pairing pin was 1234.</p> <p><a href="https://play.google.com/store/apps/details?id=com.eziosoft.ruidengdps">https://play.google.com/store/apps/details?id=com.eziosoft.ruidengdps</a></p> <p><strong>Wiring components</strong></p> <p>Wiring diagram not included - it is simple as F. But if someone needs that, i will upload some schematic how to connect all the parts.</p> <p>There are mains! I'm not responsible for any injures if you try to build same device and you don't know what you are doing!</p>
