I will model a prototype or functional product for 3d printing

Hi. I'm a student that isn't a professionalist, but I can model functional parts in CAD softwares. I offer you modeling a 3D printable part that will be printed on an FDM printer. I've designed a lot of things that work very well, even at the first prototype, so you won't be disappointed. You need to give me all required dimenstions for a prototype and photos if the shape is complicated.

I hope you will be satisfied with these models.
