Configurable Vacuum Adaptor

I am new to the 3D printing world! I am a programmer by profession, so found using OpenSCAD to be intuitive. I also dabble a little with Wood Working and have a few tools, and recently inherited a shop vac. Form that, this pipe / vacuum adaptor was born.

I have not tested the limits, but it’s worked well for the tools and shop vacs I have.

This is a fairly simple part and found that most of the adaptors I have created so far have printed well without support or making many modifications from the core defaults I use with my build plate, aside from increasing the fill density. I had one break with the default 20% fill density, 35% has worked well with standard PLA.
