Supersizing an Ender 3 V2: CR-10 Max for half the money - Ender Extender kit

Can you replicate a CR-10 Max 3D printer for half the money? In this video we are going to find out, by fitting an Ender Extender V2 kit, MDD direct drive kit, and EZR struder to the much cheaper Ender 3 V2. The results are pretty good, especially for the discounted price.

Ender Extender kit and MDD kit provided free of charge for making this video. All opinions expressed are my own.
