Downloaded the model from the Sketchup Warehouse and it printed nicely.I printed this with the Replicator 2 using silver PLA I ordered from Amazon. The original model was taken from the Trimble 3D Warehouse and was itelf a remade model of a skull that appears to have been heavily resampled.I sliced it with Miracle Grue using defaults except for raft, supports, 0.20 layer height, extruder temp at 260C. It took me 9.5 hours to print and about 2 hours to remove the support material. I gave it to my friend Ann for her birthday.I kinda liked it with the supports; it reminded me of something by H.R. Giger.
