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.
1 - seen that the previous freelancer couldn't complete the job... (i wanted to place the bid yesterday, but you already selected another freelancer :( )
2 - in order to get your parts, is necessary to have a different approach
3 - it is advisable for 3d printing to have a minimum of fillet radius (when straight angle between features the part become friable)
Regards
Bogdan
