Doosan Puma 240 Jaw Spider/Spacer Pack (1"-3" Center Diameter)
thingiverse
Job spacer for CNC lathes, but designed for a Doosan Puma 240. Will sit behind your part to space it .800" out further from the chuck in the jaws. The spider shape keeps if from falling out while rotating, and the hole in the center is designed for a M6x1.0 cap bolt, to bolt the spacer to your spindle bore cap ensuring it doesn't move (best this way as it saves time by not having to reset the spacer every time you open the jaws).
