About this 3D model

My Fan Blade Broke while doing some maintenance for my Replicator Dual Extruder Which fit with replicator and replicator 2x and replicator dual and many other printer it is kind of not easy replacing it but any way i uploaded the files for who want to replace the fan blades . Check the pictures to see what parts you will need to take out from the old fan blades BTY it has air flow like the original blade and nicely quite :)
