Hi there,
My name is Bogdan and I'm from Romania.
I'm a mechanical engineer specialized in the industrial robotic field, 3D designer and modeler.
I could design the brake assembly for you in Autodesk Inventor 2015, and deliver it in any usual CAD format, including 3d pdf.
I will also make several renderings, from different angles and different illumination.
I prefer to work on a fixed price project rather than hourly, but this is something we could arrange/discuss.
I your picture is nothing useful to see - who did thet rendering put very reflexive materials, so the outcome is mix of indefinible colored shapes.
If we'll work toghether, I will need some more info: diameter of the disk, caliper type, number of pistons, type of brake pads, the disk is ventilated or not, the hub type/diameter, bearings, etc, etc, etc.
Anyway it is time to clarify all these details.
Even I don't understand the requirement of signing the "work for hireent, I don't think will be an issue (if will discuss about collaborating on this project, I will read the agreement, and if ok, I'll sign it).
In this way, I invite you to open a msg channel here, and we'll discuss all the details of your project.
Regards
Bogdan
