Hi, I see you need someone to create or modify a part in SolidWorks that can be printed on a 3D printer. I've been working with SolidWorks for 7 years now and with the most common type of printing, FDM 3D printing, for 4 years. I have made many functional parts on my Ultimaker 3, FlashForge, and BCN3D SigmaX "FDM" printers and know the various requirements that parts must meet, like minimum feature size, support overhang issues, part orientation, etc.
I will create an STL file once your file has been modified in SolidWorks, because STL files are the ones that your printer's software will need. I will ensure that this STL file meets all technical specifications (like having a watertight mesh, having good aspect ratios to its triangles, not having multiple shells unless there are multiple interlocking parts, etc.) and advise you on printing with whatever printer you have.
If you're using another type of 3D printing other than FDM, like SLA, SLS, SLM, or PolyJet, I can also help with those (I'm just getting started with an SLA printer, got an "A" in a recent grad-level class on 3D printing of metals with SLM, and have printed a few things on a PolyJet printer too). The resolution, warping, and overhang issues are different for all of them but I'm familiar with them all.
Thanks,
Caleb
