Scroll Saw Blower Replacement Block

This is an upgrade of the little dust blower for the top of your piece when you are using a scroll saw. This is made for the old Ryobi model SC155VS but may fit other similarly designed saws. The design of the original dust blower is quite wonky and huge so I made a much better one.
This is designed to be used with the existing metal rod (12mm od) and screws that come with the part this is replacing. The air nozzle this fits is a 1/4 NPT thread flexible pipe hose (see picture). Actual threads in the part are not needed because the air hose gets shoved up into the pipe hose so there is no pressure at the threads.
I included the Fusion 360 file if you need to make changes.
