I have just uploaded printable files to Grabcad for this rest. It only fits the Prophet 2. You will also need an m8 (or close US equivalent) threaded bar, turned down to 4mm at one end and a 2.5mm rod to cut the hinge pins from. You will also need to tap the sliding block inside. And some rubber tap washers for the soft end.
