This is a redesign of brianmatters shop vac adapter for a Craftsman orbital sander. Everything is press fit to the shop vac tube and to the dust collection port on the sander. The inner tube that connects to the dust connection port is slightly recessed to allow the outer tube to fit snugly over the sander. FreeCAD, stl, and 3mf files are included. The dimensions for the shop vac tube connector are smaller, for a 1 ¼" vacuum tube.
The author remixed this model.
