Automated butane extractor

I'm looking for 3d drawings for the purpose of sales material for a butane extraction system I've been building. My R&D unit is not representative of what a finished system would look like. I also don't have CAD drawings, so what i can offer for reference will be a BOM, photos of my test skid, photos of 3d drawings of similar systems, and my technical input. Attached are photos of my test skid and examples of drawings sinless to what I'm looking for.
