Not the prettiest but it works well.  Hanger has a slight angle towards the wall to prevent the Bullworker from sliding off.  Hooks designed to prevent pendulum swing and strength.  I printed it upright (same orientation as it mounts to the wall) for added strength using organic supports +brim.    Confirmed to fit the Bullworker Steel-Bow and Bow Classic.

OPENSCAD file provided you need to alter dimensions for your specific Bullworker version.
