Simple Vacuum Hose Adapter - Rockler Dust Right Universale Small Port hose end to Rigid 2.5" Accessories

This is a really simple adapter. Small end has an ID of 38mm and an OD of 41mm. This will fit snugly into both sizes of the blue hose ends in the Rockler kit. The large end of the adapter has an OD of 58mm. This will fit snugly into the Rigid accessories (like a brush end, or one of the extension wands). The inside of the adapter has a small fillet to help with airflow, but it should print without supports (put the larger end on the print bed. I printed mine with a 0.8mm nozzle, 0.3mm layer height and 1mm line width. You could make this prettier and probably improve the airflow, but hey, this is a step up from the duct tape adapter I was using before.
