Ridgid Wet/Dry Vac (2.5 inch) to Standard Vacuum Adapter (1 inch) - Customizable

This adapter was designed to attach standard upright vacuum attachments to a Ridgid wet/dry vac locking hose.  

This was printed with supports for the collar around the larger end, but that may not be necessary.

The dimensions are customizable with Customizer or OpenSCAD.
