Dear Sir/Madam,
I do my work in Autodesk Inventor and can deliver 3D model with all relevant technical drawings with complete GD&T with BOM that You can use for production.
I'm a mechanical engineer and I can do the calculations for force needed to operate the pump, calculations for length of the lever for the pump, flow rate, etc.
If You would be interested for me to work on your project please contact me.
With Best Regards,
Drazen
