ABS with a 20 line brim. Printed using Cura as shipped with my Monoprice Maker Select V2 "High Quality", except 0.08mm layer height, 40% infill, infill speed 30. Came out pretty good, though the mounting holes were just a tiny bit too small. (Sorry about the sideways picture of the guide installed on my printer - thingiverse doesn't seem to allow one to UN rotate a picture it has decided on its own to rotate).
