5015 fan bracket for kossel m3 metal effector

5015 fan mount and duct for delta printer that using m3 aluminum effector. It is compact in design to minimize effected print area when larger fan and mount are used. I can't find any 5015 fan mount that serve my need so I design one.

It use one extra hole in the effector, I attach (you can glue it) one m3 nut at the bracket. The fan duct just snap it in place. I use E3D V6 hotend.
