I designed this base using a combination of Inkscape and FreeCAD. I used the bezier tool in Inkscape to draw the front and side view of the base. I used Inkscape to generate the letters as well. I used the extrusion and boolean operations in FreeCAD to extrude, combine and cut the parts. Following are the printing specs: Ultimaker 2+, raft, support, 0.25 mm resolution, 22% infill, eSun PLA PRO Black.
