This should print well on most 3D printers. On a Replicator 2 and 5th Generation Replicator they come out great with the following setting:
Raft On
0.20mm / Std Resolution
Minimum of 3 Shells / Recommend 4 Shells (to ensure it is strong)
35% infill
No Support
PLA (Not tested with ABS)
After printing, carefully snap/cut away the Raft so you don't damage the legs or Pincers in particular. As soon as the Raft is removed the tail should rotate up and over the Scorpionz back and Princers move and nip/grab onto things. Take care when you first rotate the pincers so they break away cleanly. Just a gentle wriggle / twist should clean it away fine.
Another tip is to put a drop of oil into each of the rotating joints to make it move smoothly and reduce the risk of any catching inside between fragments / lumps of filament that may have resulted during printing.. Free movement will help minimize the risk of fine parts breaking.
