Hi there,
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.
As I can see you have a kind of shredder which is necessary to have modeled...
On the kife, i can't see if there are any sharpened edge...
The box is 3mm SS304...
I could provide you the model in different cad formats (iges, stp, stl, etc) and 3d pdf (for the assembly and each parts...
(for the prototyping/manufacturing purposes is better to use iges/stp files - if you want to 3d print the parts, stl would be enough, but i need you to specify this in order to apply the proper tolerances.
For any more questions we could chat here.
Regards
Bogdan
