Einhell Shop Vac - 50mm Hose Parts

thingiverse

Parts to replace the current 32mm sized hose and tools on my Einhell shop vac with a larger diameter (50mm) hose - I found I kept getting clogs in the hose vacuuming up chips and swarf from around my machine tools. All parts assume that the hose has an ID of 50mm and an OD of 60mm, as per this hose that I've used from here: https://www.ebay.co.uk/itm/Flexi-Hose-50mm-2-Metres-Wet-and-Dry-vacuum-Gutter-Vacuum-Cleaner-Accessory/143361287519 Thread on the Vac Screw Sleeve is sized for the Einhell vac I have (BT-VC 1500 SA) which is an odd-ball M68x5; I've sized it at M65.5x5 for an easier fit. The 'thread' used to engage with the spiral ribbing on the hose is a 2mm triangular section spiral with a 6mm pitch. I was going to use glue on the hose to stop it from coming out, but it's a tight enough fit that when the parts are screwed on to the hose the friction is enough. Step files have been included if you want / need to change anything. Update 11/04/2020 - Added new nozzle for cleaning out T-Slots on a mill (fits 14mm or 9/16" slots) and a screw on hose hanger.
