I have 7 years of experience on SolidWorks and AutoCAD. My work is always precise and presentable.
Stl files won't be very useful for the assembly, it'd be better if you have 2d drawings of the parts.
I'll make the 3d model of the assembly and an animation (won't be very sophisticated) for the assembly process showing how every part fits in the assembly.
I am eager to prove my self as a successful and experienced Freelancer, and I will work on your project for 8+ hours per day and I am looking forward to receiving your review about my work.
