About this 3D model
Here is my first public model. The adapter allows you to use Parkside X20 Team battery packs in older Einhell cordless screwdrivers like the Akku-Bohrschrauber LE-AS 18-2. I printed everything with default settings and a 0.4mm nozzle. It's a bit tricky to insert some of the battery metal connectors. It took me a while to position them correctly. I soldered in some M2 threads on the backside to connect wires by clamping them with screws.
