You can print everything but the finger distals with no support. The Ody Hand is essentially a Talon Hand, but with fewer fingers. Ivan Owen has made an excellent Talon Hand tutorial, and the instructions are almost identical.

The cable anchor for the Ody Hand uses set screws. I used 0.05" trimmer line (like for landscaping) for the cables, and found that if I mount the anchor forward and close to the cable guide, the hand will open without elastics. The cables push and pull. In the photos here, you can see that the extension channels are left open. If your hand is not opening satisfactorily, you can install elastics. But if possible, avoid elastics, since they make it more difficult to close the hand. 
Here is the hardware list for a build at the scale of 1:
wrist hinge: (2) 8-32 x 5/8" flat head hex screw; (2) 8-32 nylock nut
Anchor mount: (3) 3m x .5 x 8mm flat socket cap screw; (3) 3m x .5 cap nut
Cable anchor (3) set screws 6-32 x 1/4
Cable guide: (4) truss head sheet metal screws #4 x 5/8
Palm leather mount: (16-20) truss head sheet metal screws #4 x 3/8
Leather to arm bars: (8) 6-32 x 3/8" flat socket cap screw

+ a layer of 1" nylon webbing: (1) 6-32 x 7/16" flat socket cap screw
+ 2 layers of 1" nylon webbing: (1) 6-32 x 1/2" flat socket cap screw

3 pieces, each ~a foot long 0.05" round trimmer line (landscaping type) for the cables. Fingertip ends of the line are melted into balls with a lighter so that they catch in the tips.
