4010 Blower Fan Bracket for M3 Metal Effector

Can't find any fan bracket for my use, so I design one. Small bracket perfect for my M3 metal effector use.
You can use Creality fan duct or the included one, if you use creality fan duct, make sure not the offset one, it should blow at the center.
I use one m3 nut, push inside the nut hole at the bracket.
If you want to lower the bracket, just use washer.

Update: Added M2 fan screw hole version as requested in the comment.
