You can use the tubing from a Zing Bow. Need some M4 screws and nuts (4x long, 4x as well as some small ball bearings to put in either side of each roller "pulley" (don't remember the size). Works better than the Zing bow my son had that broke.
*Updated files to the v3 bow, brace, bracket, and the correct roller (pulley) file.
