Dewalt 20v Max power tap

prusaprinters

<p>These components can be assembled, by stacking, to construct various items powered by the Dewalt 20v max batteries. &nbsp; Three examples in the pictures are a power tap with anderson powerpole connectors, a power tap with a pigtail, and a three place USB 5v 3A charging stations. &nbsp;Configurations can include a cap with a cutout for a voltage readout.</p><p>In the examples shown, the voltage readout was of this type: &nbsp;<a href="https://www.amazon.com/gp/product/B00YALUXH0">https://www.amazon.com/gp/product/B00YALUXH0</a></p><p>The USB 5v chargers were of this type: <a href="https://www.amazon.com/gp/product/B01HXU1C6U">https://www.amazon.com/gp/product/B01HXU1C6U</a></p><p>The Anderson powerpoles used are this style connector: <a href="https://powerwerx.com/anderson-powerpole-connectors-30amp-unassembled">https://powerwerx.com/anderson-powerpole-connectors-30amp-unassembled</a></p><p>The battery connection terminals were cut from 1" x 1/32" brass stock. &nbsp;Each was an 8 - 9 mm slice off the end. &nbsp;For me, the easiest way to cut was to scribe on both sides, then use pliers gripping next to the scribed line to flex back &amp; forth until the piece fractured off.</p><p>&nbsp;</p><p>The components consist of the following, all named “dewalt 20vmax power tap” with an appended identifier.</p><p>Part &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Description</p><p>A - &nbsp;the base component that engages the battery</p><p>Bn - a middle layer component that is attached to A via two 3mm screws</p><p>B1 - version with two cutouts to accomodate USB charger boards</p><p>B2 - version with one cutout to accomodate a USB charger board</p><p>B3 - version with one cutout to accomodate a pair of 14 awg wires.</p><p>B4 - version with one cutout specific to accomodating a joined pair of Anderson power pole connectors. &nbsp;It has a pair of ribs that engage the depressions on the connector sides to hold them securely in place.</p><p>Cn - a component that snap fits to a B component. It may be a cap or expansion space.</p><p>C1 - A cap with a solid top.</p><p>C2 - A cap with an opening sized for a voltage display.</p><p>C3 - An expansion space to accomodate a device up to 80mm x 50mm x 17</p><p>Dn - A cap for a C3 component</p><p>D1 - Solid cap</p><p>D2 - Cap with opening for voltage display</p><p>&nbsp;</p><p>All components should print without need for supports. The electrical contacts should be mounted through both A &amp; B components used. &nbsp;Users may want to include an appropriate fuse for their application, either internally or externally. &nbsp;I used servo tape for securing electronics in place.</p><p>Some early versions seen in the pictures had A&amp;B components glued rather screwed together. Using screws limits the USB charger build to &nbsp;two ports rather than three.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>
