Countryside battery to Nutool adapter

thingiverse

The Countryside (My Project 20V fro Kaufland) battery to Nutool electric screwdriver adapter. As Schweiger mentioned, it also should fit to Tryton 20V, MyProject 20V, Countryside 20V, Warcraft 20V, Snapfresh 20V, Gardenic 20V batteries. The FreeCAD project also have dimensions of two kind of contact plates - one to battery and other one for the screwdriver. Connection poles (PLUS to PLUS and MINUS to MINUS) plates is made with screw 3.5x15 mm with cone head and short piece of copper wire (from FTP, one wire without isolation per pole contact) - see photo. In addition it is possible to attach DC Jack 2.1/5.5 mm socket as internal nut diameter 12 mm. This Jack can be used to charge (rather slow) the Countryside battery with original Nutool charger. This case the charger need to be connected to MINUS to MINUS (-) and PLUS (inner in charger plug) to DC contact on battery. If you have Countryside 20V fast charger, you don't need it. Update 5.11.2022 Some fixes in Nutool adapter and lock after in field tests. The adapter use two parts, each one for other type of battery and tool. In future I try to design Countryside battery adapter for Makita tools. Update 4.02.2023 I designed adapter from MyProject 20V battery to Makita (an compatible) tools, so I need some time to publish. Stay tuned. FreeCAD source attached.
