macdaddy collapsible stock

Collapsing brace/stock for macdaddy.

Requires:
- 3' section of 1/4" steel rod (can be found at most hardware stores)
- two M2.5x20mm screws and nuts
- spring from a pen (I used a pilot G2)
-dremel or similar rotary tool


Assembly instructions:
1) print all parts and remove all supports. The "button" part will need to be sanded/filed to slide freely within the housing. Special attention should be paid to the inside of the housing where the button will slide up and down.

2) Assemble the housing. Insert the button, then the spring, then the retaining plate from the bottom of the housing. Fasten everything together with the two M2.5 screws.

3) Cut your steel rod into two 10" sections and two 8" sections. Use the 8" sections for the brace in order to fall within the length-of-pull limits. Cut your locking notches approximately 1" from the end of the rod. These notches should be 0.15" in width and 0.10" in depth, but I would recommend cutting a little bit then test fittin
