18650 inline cell press

A press that lets you push two 18650 cells together 

The cells are aligned and held together which allow you to tape the join

The press end is an M5 and takes a CNC kitchen M5 long insert. It should probably work without the insert

If you ask i'll drop in a nut so you can use a nut instead

If you are wanting a nice neat join then use the jig for welding them
