These are cookie cutters designed from the character logos for each of the B2-universe kids in the web comic Homestuck (http://www.mspaintadventures.com).Thin-Wall Warning: These models use thin walls of about 1mm in thickness. Be sure your 3D printer can do thin walls, and that your gcode generation software is set to do thin walls. In Slic3r, thin walls may not have infil, and the print won't come out right. Be sure to check your gcode to make sure the thin walls are solid
