Hose-end Drain Unclogger
Description
This Is A Printable Take On A Tool From The "Big Box" Home Improvement Centers, Which You Put On The End Of A Hose And Stick Into A Clogged Drain. When You Turn On The Hose The Bladder -- Toy Balloon In This Version -- Expands To Make A Seal Against The Inside Of The Pipe While A Jet Of Water Pressurizes The Drain And Clears The Clog. The Commercial Version Works Quite Well, But Costs Over Us$20 And I'Ve Blown Two Of Them Out By Applying Too Much Pressure. This Version Can Be Modified, If You'Re Comfortable With Openscad, To Whatever Size You Require. (And Yes, As My Wife Observed, It Does Look Rather Phallic.) It Requires Cawalke3'S Female Hose Fitting Stl "Hose_Fitting_10Mm_V3.Stl" From Http://Www.Thingiverse.Com/Thing:10189. The Stls Are Sized For 3/4" Pvc Pipe, Which Is What The Condensate Drain On My Hvac Is Built From.
