Hi Reyan,
This is Bogdan from Romania.
I'm a mechanical engineer - specialized in the industrial robotic field, 3D designer and modeler (from time to time and some projects I could make the functional prototype too).
I'm doing product design, industrial design, reverse engineering, ideation, etc.
I have over 15 years experience working on various systems/devices across multiple industries, from concept to launch.
1 - hope inventor 2017 is ok with you (if you use an earlier version will not be able to open the files, but i can export as step, iges, sat, etc)
2 - besides the given dimensions, i will need the type of bike and if possible the dimensions and fixing point positions...
3 - about the materials is a whole discussion to have... but for sure no 3D printed parts (3d printed metallic parts are very expensive, and the plastic is friable - at the first contact with something will crack)
i'm aware my bid is above the rest of the freelancer, but you will see the difference :)
we could discuss all the details here...
Regards
Bogdan
