Machine-battery adapter for a machine that originally uses a Parkside PAB-18 1.5 A1 battery. This adapter enables to mount Einhell Power X-Change batteries to the Parkside machines.

Extra stuff you need:

some wiring and a soldering station
male and female connectors (e.g. [https://www.aliexpress.com/item/4000506571122.html](https://www.aliexpress.com/item/4000506571122.html) and [https://www.aliexpress.com/item/4000104101344.html](https://www.aliexpress.com/item/4000104101344.html) )
some glue to glue the contacts into the adapter
some screws to fit the two parts together (I used M4)
a spring, e.g. from a ball pen
 

Notes
These parts need minimal supports if placed upright (except for the clip).

Things were designed to the point. So if your printer isn't as accurate as mine, these things might not fit as they'll be too tight.

Print with more infill if you regularly remove the adapter(s) from the machine.

Post-Printing
If the parts are too tight for your machine/battery use a little file for post-processing or scale the part a little bigger.
Cut out the printed supports with a sharp knife.
The screw holes of the Parkside adapter are made for a tap and die, but might also be used to directly hold the screws.
