CNC Tiger Claw (Toe) Clamps M6 Hardware

I really liked the toe or claw not sure of the exact name of these but I liked them. 

This is my take on this style of CNC hold down clamp. 

I have included a thumb screw as well several clamp faces to try out. 
Please provide any feedback of other faces that might be useful. 

These clamps all use M6 hardware. 
Each Clamp will need an M6 Nut inserted from the bottom as well as an M6x18 or M6x20 screw to connect the toe clamp top part to the main body, bottom part. 

I have recommend 5 walls, 5 Top and Bottom and 25% infill but you can play with that to get the desired outcome you want.
