Designed these feet and extensions to allow me to re center the laser onto the work surface after moving it around or raising it allow for etching larger items. Have only gotten around to printing the 50mm risers. Will be printing the 75mm risers when I can and adding pictures. Used 4 screws per foot to mount down to the surface. Machine feet rest in the openings to center it to same spot after raising or lowering. Extensions offer risers that still center the machine onto the work surface and allow for 50mm or 75mm of additional Z-axis space for larger engraving projects.
