bare power supply cover

prusaprinters

<p>I had a few of these bare 12v 30a power supply units around that are cheap &amp; work well but have a virtually unprotected terminal strip for the 120v &amp; 12v connections. I made up a cover for the terminals end of the supply that includes a fused, switched AC connector, a voltage readout and 3 12v supply connections made up of Anderson Power Pole connectors.</p> <p>I made use of the Anderson Power Pole virtual punch by loughkb: <a href="https://www.thingiverse.com/thing:2783449">https://www.thingiverse.com/thing:2783449</a></p> <p>The cover is held in place by 3 M3 screws (2 on one side, 1 on the other).

No need for supports. It can be printed using a coarse setting (I used 0.28 mm for one print) without issue.</p></div> Post-Printing</h3> <p>Most components should snap in place, but glue can be used if needed for the display and power inlet.</p> <p>Use appropriate wire thickness for your intended application &amp; crimp or solder fittings as needed for good mechanical &amp; electrical connections. Use heat shrink or equivalent as needed to ensure a safe construction.</p> <p>Wire length should be just long enough to make your connections before securing the shell on the supply. Pre-bending the wire a bit can help fold the extra neatly as the shell is pushed onto the supply.</p> <h3> How I Designed This</h3> <p>The model was done in Tinkercad &amp; can be found here:<br/> <a href="https://www.tinkercad.com/things/ezNIfDOuzyn-power-supply-cover">https://www.tinkercad.com/things/ezNIfDOuzyn-power-supply-cover</a></p> <p>You can ungroup &amp; modify if different mounting hole positions are needed.</p> </p></p></p> Category: Electronics
