Material: PLA
Printed with a 1.2 mm shell thickness, 60% infill and 0.1 mm layer height.
I added a brim on the Ultimaker 2 with Cura, but there was still some warping, nothing serious.
I usually design things in Sketchup to print stuff on my UM1 or UM2. The designs are always accompanied by their source files for editing and a collada file for printing but if you want a particular format, just ask.
