For an easy installation of the Nebula Camera onto an existing frame, you need to replace the original screws with longer ones.
I derived the original idea from
Ender-3 V3 Z-Axis Nebula Camera Mount by EBD Design Studio | Download free STL model | Printables.com
I modified all the dimensions and the position for the mount.
Enjoy it!
