Remix of "3D printed Laser Engraver"

This is a remix of this laser engraver:

The outer dimension is 420*420mm, and the laser is a 2.5W blue.

I've add a Y motor spacer printed in PETG, so Y axis will be more rigid and solid.
I've also add an endstop holder, it can be used with M5 screws...

Edit.
Added a few photos of some work...
