What a shop-vac 2-1/2 inch hose to 1-1/4 inch accessory adapter is
A reducer that lets a 2-1/2 inch Shop-Vac or Craftsman hose use 1-1/4 inch accessories. The wide end is a socket that pushes over the hose cuff (about 63 mm at the tip with a slight taper), and the narrow end is a 32 to 34 mm tapered male spigot for 1-1/4 inch nozzles and crevice tools. A 40 mm long transition keeps airflow smooth, walls are 2.4 mm. Print upright in PETG.
Ridgid and Vacmaster hoses of the same nominal size can differ by a millimetre; measure your cuff first. Open the adapter in SpeakCAD at no cost, change both diameters in the viewer or the chat, then download the STL.
