Since the Ender-3 V3 Mega's camera configuration supports the Nebula Camera as an optional accessory, installing it on the Ender-3 V3 Mega requires printing an auxiliary mounting bracket and auxiliary mounting screws before it can be attached to the machine. This tutorial has been created to serve as an installation guide.
The auxiliary mounting bracket and auxiliary mounting screws need to be printed by the user. The auxiliary mounting components can be found in the machine's built-in local models.
