Layout the items you want to print in Makerware, then rotate the view so you are looking at your models from underneath. Add the ear raft and copy and paste it as many times as needed. Overlap it with the edges of your model to increase its surface area on the build platform - see the attached images for examples. I tend to space them 10 to 20 mm apart and only overlapping 0.5 to 1 mm seems to work best.
If you want to slice and print with ReplicatorG you can use Makerware to layout your objects, attach the ear rafts and then export the STL file back to ReplicatorG. Sometimes ReplicatorG/skeinforge will complain but it will print.
This model was derived from an ACIS solid so Makerware, ReplicatorG and Skeinforge have no trouble with it.
