This is a remix of Devin Montes' Ender 3 files so that they work on an Ender 3 V2. His original tutorial for Simplify3D can be seen here.
The printhead bracket attaches to the printhead with two small screws. I'm not sure what specific size they are. I just happened to have some spares from the original printer kit.
The bracket that holds the remote trigger sits on the left end of the X rail.
The finger file is printed in TPU to give some flex when pressing the button.
A custom time lapse Cura script was used to set up the printer motion (screenshot of my settings below). A link to the script and instructions for setting it up can be found in Chuck Hellebuyck's video.
One main design flaw is that the remote is in the way whenever the printer homes. Suggestions for fixes are greatly appreciated!
