The file 'Grid For Diode Laser 3D Printer Model' is (stl) file type, size is 18.0KB.
Simple grid using PLA, which works surprisingly well. Diode lasers do not burn hot enough for long enough during normal operations to really affect the plastic.
Can be scaled in slicer to any size. I used my ender 3 and printed the file at max X and Y.
Print at 100% infill
