For changing old 18v tools so that Parkside and florabest 20V battery can be used. although Lidl calls the batteries 20v it is only 18v. 5 cells of 3.7 as in other 18v with lithium cells.

I make the stainless steel power connection and glue it down, or I make some notches with a file and weld them with a 3D pen. CE3_template.gcode is a template to draw around.

With this part it is easy to change old 18v tools from Powercraft, Power Cdact and Tool Mann. For other makes, I have drawn two parts for fixing glue after the handle is cut over. They are in the sketchup file but have not yet been printed in that version.

NOTE It is important not to stop before the battery is completely empty. when it is not the tool that belongs to the battery. The battery can not be completely discharged.
