About this 3D model

This is a vacuum hose adapter that allows a Shop-Vac 45mm hose to connect to a Kent CNC dust collector which has a 4" diameter vacuum port. The Kent CNC dust collector I just purchased has a threaded 4" vacuum hose connection, so this has an interior thread on the 4" section that fits directly onto it very snugly. The other end allows a push-fit onto the 1.75" hose from my Shop-Vac. I largely work in SolidWorks these days, so that's the CAD file format uploaded here.
