Fully Parameterized Shop Vac Adapter

After buying another shop vac which has a 2.5" hose and acquiring more power tools, I've quickly realized there's a huge variety of vacuum hose/hose hookup inner and outer diameters, some of which don't even match their stated "nominal" diameter. This has made it very handy to have a fully parameterized model to allow me to quickly design and print a new adapter for each tool I acquire. I made this heavily remixed version of @cfinke's design and have been tweaking it over the past few weeks, and I think it's at a point where it's ready for sharing. The only .stl file I attached is an adapter for connecting a 2.5" nominal diameter shop vac hose to a 1.25" nominal diameter tool vac port. The actual OD of the tool/to side is exactly 1.25", but the vac side actually has a 57.7mm ID, which means neither its ID nor OD are 2.5". However, it seems to fit my shop vac fine, and also lines up with the size of my table saw, so I guess this means it's somewhat standard?
