Wet Vac attachments

Wet Vac attachments. This Thing is a Work-In-Progress ! I tried my pieces and am very UN happy with results with the amount of suction. Ok 3/4" ID w/ straight exit tube had a lack of suction and the 5/8ID tube at an angle with the output necked down actually had positive air flow, not negative ! OPPS ! They fit nicely. I am revising, reprinting and will test again this weekend. I will post new files after I test them this time. Sorry. The story behind these parts. I had a large tractor tire go flat, come off the rim and gather water. Before I reseated it I wanted the water out of the tire. I could not fit my hand inside or get a Wet Vac hose inside. I looked around the barn for something and found a HVLP paint gun and sandblasting gun for inspiration. Having a large volume suction spray gun adds other possible uses than just starting a syphon. I have several Wet Vacs and even a couple high volume – low pressure fans just waiting for the next use. So I grabbed a small diameter tube and modeled it, but only 3” long. Dimensions are rounded in JPGs. My parts have fit properly as printed, pretty happy with that! So I made Wet Vac-1.5 to 1.18 od connector pipe.stl From that model I created the part with a suction hose connector. I figured ¾” ID tubing would be easy to find. I have printed this one and had good air flow blowing past the hole creating a nice vacuum. So I made Wet Vac-75 id suction tube straight.stl Then I thought funneling it would increase pressure and suction. So I made Wet Vac-75 id suction tube w neckdn.stl I liked the neckdown and thought it might be handy to have a blower attachment. So I made Wet Vac-1.5 to .44 neckdown.stl Then I went to the store to get tubing. I was in luck they had a whole selection of tubing clearance. Would you believe not one inch of ¾” ID ! They did have a have a roll of 5/8” ID x ¾” OD tubing. So I made Wet Vac 625 id suction tube w neckdn.stl Then just to see if even more output diameter reduction increased suction I modeled Wet Vac 625 id suc tube w half output.stl And yes, it did occur to me that most people will have a Wet Vac and not a blower. At least one of my Wet Vacs does not have a way to attach to output. So I took the design to the logical beginning point and made a connector for the 5/8” ID tubing to the hose so you can just attach it to Wet Vac and suck it into Wet Vac. So I made Wet Vac 625 id suction tube STRAIGHT.stl Also included is the Autocad 2010 file. More to come. I will probably create an adaptor for the standard large to small tubes. I am also think of making a couple hose attachments for some special purpose ideas.
