ENDER 3 DRAG CHAIN
First off, none of this is possible without JohnnieWhiskey on Thingiverse. So go buy him a beer! These are all his files that I am just giving an easier guide of what to print. Thank you Johnniewhisky!!!! Also, the parts are renamed to make it easy.

WHAT TO PRINT AND HOW MANY
Take off triangular cover on the hot bed and replace with the adaptor. 12 to 14 links are for the hot bed, the rest are for the hot end (gantry/X axis). You may want more on the hot end chain to get you closer to the extruder.
