Here's the Wyolum logo for adding to projects. The version here is relief (stands out) but you could easily make a cutout too. Make sure the DXF file is in the same directory as the OpenSCAD file.
UDPATE: SCAD updated to make the logo into a module, can also be flipped for printing on the bottom of things
e.g.: translate([0,0,0])wyologo(flip = true);
