Improve safety and durability of TwoTrees laser engraver

The set includes elements for:

improve your twotrees laser engraver durability with cable strain protections for the X/Y axis and cables exiting the control board. All have small 1.75 mm holes to use printing filament as cable guides (PETG would be better, as PLA may too brittle and snap). A small element allows avoiding the wires being caught by the nut and thread at the back of the X carriage.
improve your safety with the laser shield. The top element replaces the original Plexiglas plate on top of the laser electronics. The feet are designed to raise the engraver over a 26 mm thick wood oven stone (which resists high temperature and with very rough surface scattering the laser beam) to protect the workbench.
improve the capability of your laser engraver with the addition of end stops on the X/Y axis using 3D printer switches.
I also include my mks DLC configuration that you can import and upload in your laserGRBL (grbl->grbl configuration). I still have no auto homing, but the end-stops are functional.
Finally, you will find the file to add practical custom buttons from the file MyButtons.gz
