Working Water Wheel & Mill

thingiverse

I designed this for my wife and never intended to release it to Thingiverse. I got so many people asking for it on Reddit that I went back in and made some design improvements for you. If you find a better way to do something, try it! Video: https://www.reddit.com/r/CR10/comments/c0d8o6/designed_and_printed_on_a_cr10_pro/ Use caution when selecting layer heights. Most parts can be low resolution (0.2) but the pump, impeller and hose nozzles should do better around 0.08. You may want to experiment with impeller designs as I am still trying to quiet the pump down. It's possible my motor just allows too much shaft movement and the impeller pulls itself into the face plate. Still works, but it is a bit louder than I like. Be sure to seal the pond after painting. I tried outdoor clear flat but it still soaked up some water. I have since painted clear resin over the painted and detailed pond bottom. If your wall support pegs result in a tight fit due to your printer settings, carefully sand the pegs down until you get a snug fit. Glue the flume nozzle into the flume end with some E6000 or cement. You want a rigid fit so that the flexible hose doesn't unseat the nozzle. Glue your flume onto the side of the structure being sure to angle it down so it rests just above the wheel without touching it. Send your motor wires up through the small hole in the floor plate and route the tubing through the large hole. You will also need: - 24.3mm diameter cheap electric motor with a 2mm shaft (or resize the pump housing and impeller to match your motor) - Small electrical wire to connect motor, switch and batteries - Approximately 4.5 volts of power (I used 3 D-cells wired in series. A 9-volt works but may send too much water) - 5.5mm inner diameter (ID) flexible tubing, approximately 6" (Needs to fit over nozzle ends) - 3.8mm diameter x ~32mm long metal pin for wheel axle - Washer to fit on pin between wheel and building - Some thick PTFE grease to lubricate and seal impeller/pump housing and lubricate wheel pin - An on/off switch that fits the 5.75mm hole in the back of the roof wall - Four small screws to hold the pump face plate on. Just predrill the holes if your screw is too big, I left some room.
