Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer, designer, modeler and inventor with over 15y experience in designing, modeling and effective manufacturing of different products, devices and systems which spans across multiple industries.
I could make the model of your fan, taking care of the torsion angle of the blade (if it's an axial fan) or the evolvente (if is a centrifugal type).
Will be very useful to have more info about your new fan and what make it stand out.
I will suggest you to open a msg channel here and we'll discus more.
How I work and what I'll deliver: based on your input (drawings/sketches/indications/image references) I will make a first/rough model. On this model, together will adjust/modify/change shapes/dimensions/features until desired outcome is reached.
I'll deliver you the 3D model and its components in different CAD formats (iges, step, stl, etc), 3D pdf so you'll be able to open/view the model into the regular Acrobat Reader, BoM (bill of materials), execution drawings and relistic renderings (in Keyshot).
