There are several areas that are impossible to machine... they could be injection molded but not machined. Sharp inside corners in the Z axis are not machinable... if they have a radius they can be machined. The smaller the radius the longer it will take to machine as the tool would be small. I can only view a stl file and can't make a solid out of it... Is there some reason you selected PVC as the material? >From a plastics manufacturer: . Materials that are resistant to bromine are few: titanium, fiberglass reinforced plastic (FRP) and PVDF. PVDF was considered the best choice because vessels made of FRP have been known to blister and fail prematurely, whereas titanium is very expensive. >From Cole-Parmer database: Listed as very good; viton, pvdf, teflon, noryl, kel-f, hastelloy-c. Ti was listed as poor. Another source listed stainless steel but did not recommend Ti No one listed glass which is absolutely resistant to bromine but not much of an engineering material. Clearly YMMV. Good luck.
