1 adapter that does it all! Will NOT fit newer lithium tools
This is a PETG 3d Printed Dewalt lithium battery (not Flexvolt) to 18v Snapon Nicad tool adapter ready for use on drill(model CDR4850), 1/2" impact model(CT4850H0), flashlight(Model CTLED4918). Also with the grease gun! It will NOT fit the 3850 series with battery that goes in tool. Will NOT fit newer lithium tools . I can't guarantee that it will fit all the Ni-cad tools, I don't own all the tools to check first. If you come across tools that it doesn't fit please contact me so I can make a list that it doesn't work with and/or adapt the adapter. ( LOCKS in place NO modifications to tools)  Pictures show the tools I own that it fits.   
Complete adapter ready to rock and roll. Must remove adapter before charging.  Only use charger made for new battery. Example Nicad/Nicad or Lithuim/Lithium  Not Lithium on Nicad charger. Not responsible for Misuse/tool or battery damage Do not store in above 100 degrees  example: hot car with sun beating down For international buyer is responsible for any customs, duty,  tariff  charges. 
(This does not come with batteries or tools just adapter) Instructions: 
1.  Insert tool first all the way(if the tool isn't all the way in the battery will not go in all the way)
2.  Insert battery it will need some pressure to push up the locking mechanism.  Push until the battery locks in place.
If it is really hard to push up make sure the tool is all the way in. Tool removal:            
1.  REMOVE Battery first
2.  Then remove the tool.
Very simple to operate please send me an questions or concerns so I can correct any issues that come up!  Thank you
