Dewalt 20v Max power tap

thingiverse

update 6/7/2022 - added "dewalt 20v_max_power_tap_A1" with flat head screw reliefs printed in place to allow assembly using flat head 3mm screw inserted from bottom without requiring manual cutting of screw head relief. These components can be assembled, by stacking, to construct various items powered by the Dewalt 20v max batteries. 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. Configurations can include a cap with a cutout for a voltage readout. In the examples shown, the voltage readout was of this type: https://www.amazon.com/gp/product/B00YALUXH0 The USB 5v chargers were of this type: https://www.amazon.com/gp/product/B01HXU1C6U The Anderson powerpoles used are this style connector: https://powerwerx.com/anderson-powerpole-connectors-30amp-unassembled The DC buck circuit for the 13.8v supply was like these: https://www.amazon.com/dp/B09P61S9CX The battery connection terminals were cut from 1" x 1/32" brass stock. Each was an 8 - 9 mm slice off the end. 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 & forth until the piece fractured off. The DC buck circuit was like these: https://www.amazon.com/dp/B09P61S9CX The components consist of the following, all named “dewalt 20vmax power tap” with an appended identifier. Part Description A - the base component that engages the battery, screw holes for assembly with 6mm cap head screws from above w/out nuts A1 - a base component with reliefs for flat head screws inserted from below & nuts on top Bn - a middle layer component that is attached to A via two 3mm screws B1 - version with two cutouts to accomodate USB charger boards B2 - version with one cutout to accomodate a USB charger board B3 - version with one cutout to accomodate a pair of 14 awg wires. B4 - version with one cutout specific to accomodating a joined pair of Anderson power pole connectors. It has a pair of ribs that engage the depressions on the connector sides to hold them securely in place. Cn - a component that snap fits to a B component. It may be a cap or expansion space. C1 - A cap with a solid top. C2 - A cap with an opening sized for a voltage display. C3 - An expansion space to accomodate a device up to 80mm x 50mm x 17 Dn - A cap for a C3 component D1 - Solid cap D2 - Cap with opening for voltage display All components should print without need for supports. The electrical contacts should be mounted through both A & B components used. Users may want to include an appropriate fuse for their application, either internally or externally. I used servo tape for securing electronics in place.
