Powerplus (portercable?) 18V tool - X20 Parkside battery adapter

Use a powerplus tool with a parkside Lidl cheap battery
I don't know if this is compatible with porter cable, i only own a powerplus one, but this seems same color and design as portercable..
I'd be nice to have comments about that.

I found a nice idea to use the plastic as a spring, that make the build easier, and cheaper.. But to remove the adapter from the powerplus tool, you need to use a flat screwdriver (4-5mm) so you can unlock it.

Freecad file included
Please inform me of any problem you find
Should be good, be carefull on the wiring.
Detach X20v battery to recharge on the X20v charger, not on the powerplus one!
Use at your own risk, i am not responsible of any damages.

Powerplus side is totally designed by me, parkside'side inspired from https://www.thingiverse.com/thing:4543309 (Thanks you! The remix feature is buggy)
