More tool heads will come soon. I use 40% infill, and some hardware from Ace Hardware to secure tools to handle, and for the pivot point. Pivot point uses 1" ¼ thread bolt & Locking nut, and the tools are secured in with a ¾" 6-32 thread machine screw & bolt. I made this tool so I could open laptop bottoms easier, because traditional pry tools dont put enough force on laptop clips to separate them. 

Feel free to comment, and i will do my best to respond.
