Hello, I am Jovan Devic from Banjaluka, Bosnia and Herzegovina and I am a Mechanical engineer since 2019. I have a lot of experience in working with 3d modelling, about five years I am active in SolidWorks.
I've read your all description carefully and understood your requirement, so I think I can do your project perfectly. Your project is very wonderful. I have good experience in this field. So far, I have accomplished many tasks like this. If you hire me, you will get the great results.
I have done a lot of projects in my firm where I am working in 3d modeling department. I have made plastic boxes, plastic replacement for gear and other things, mountain brackets, stove for kitchen, air conditioner, power supplies, few parts for bicycles and a lot of other projects.
Right now, I am making my own course on Udemy and it is about plastic and sheet metal in SolidWorks.
If you have any questions I will lovely answer to you.
I also noticed that your example in attachments is not fully defined, when I am doing sketch it is always fully defined.
Best regards, Jovan Devic, Mechanical engineer
