EDIT: The second print profile is a completely different design that allows the wheel to be assembled within the body of the sewing machine, thus allowing the wheel to turn. The wheel is also rounded, which creates a much more authentic model. 

This is my first model design. I coulnd't find any decent antique sewing machine models anywhere, so I created this entirely in TinkerCad.

Best results for the sides and base are variable layer height. I've included two types of wheels, one rounded and one not. 

Simple, self-explanatory assembly, some glue is required.

Thanks, let me know what you think!
