I am often bothered that the ribbed vacuum hose jams on the workbench edge. To provide a smooth operation I made this small vacuum hose holder that can be clamped on the table or secured with a bench dog with 20mm diameter. The clamp works best for my purposes printed with PLA XT from Colorfabb with 1.2 mm outer shells and a 50% infill on an Ultimaker 2. The material is stiff enough to hold the hose tight and is still easy to place and remove.
