Description
I've remodeled the adapter from scratch because my old adapter (https://www.printables.com/model/98138-battery-adapter-einhell-power-x-change-general-pur), that was based on another design, has some issues.
You will also need:
2 crimp spade connectors (e.g. https://www.aliexpress.com/item/100pcs-50pairs-6-3mm-16-14AWG-Female-Male-Electrical-Wiring-Connector-Insulated-Crimp-Terminal-Spade-Blue/32846771914.html )
hot glue
appropriate crimping tool
wire
One photo (it's from an early iteration) shows how to put the spade connectors in place.
Improvements over the old version:
easier to print in both orientations
way better fit, the old one was too tight in my opinion
the cables of both poles aren't strictly separated anymore and there is more room to be more flexible with cable management. Maybe even a small buck converter fits there
indicator for plus and minus
Support recommend if printed as uploaded. The last photo shows how i printed it with support. I've used 4 mm yx separation from object.
If rotated by 180° no support is needed.
