ball valve remix with 1/2 in hose fittings

thingiverse

Ball valve remixed normally when I see that a thing does not have an actual picture, this means it hasn't been printed and therefore none of the parts will fit as actual dimensions aren't the same as 3D-printed parts. I run away like the wind because it will take days to remix to make parts fit and work. This thing was exactly as I thought it would be - none of the parts fit. All parts had to be remixed and reworked for function. If the original designer is reading this, I upload the concept of the design for demo purposes only. Some of the parts were more complex than a 3D printer can print. 3D printers cannot print rounded O-rings; they must have sharp edges. The handle had more complexity than a 3D printer could print. So, this did take me two days to remix, but this design makes the work worthwhile. Only parts that need supports and raft are the handle and ball prints, both of which should be printed with a 100% infill - solid. To put this together, the ball and ball butts have to be really smooth. To make the ball buts smooth, I used a round head bolt and took a Dremel tool to rough the head up to make it into a round head file for the drill. To make the ball smooth, put a nut and bolt through the hole and use the drill and sandpaper to smooth and round the surface. Then dip all parts in acetone for 2-3 seconds - no more than 5. This will make all the parts look like factory parts, which is critical for parts that don't leak. Use acetone to melt the handle to the ball. The output tubes are made so they won't dry fit; don't worry if they don't. This is deliberate. Use acetone to melt the tube ends to valve parts. Also use plumber's grease on the rubber seals and ball and ball butts - this will help seal this thing. I have added a rubber washer at the end of this thing, which is not there to seal the end; it's there to put pressure on the ball and butts to seal those. Only tighten the end nut for light pressure on the ball - too much and it will break the handle off. I hope these instructions are understandable? I won't get upset if you leave me a note saying what in the world I'm talking about, as I've never been any good at giving instructions? I have scoured Thingiverse for ball valves. I have an idea for a ball valve with way fewer parts and better seals. Maybe someday I'll design and post it, but for now, I made this for my trommel project in progress, and all it has to do is work, so they're printed and working.
