I saw something like this in a dog video some time ago and thought what a great project to try to remake for 3D printing. It was a little ambitious for me but in the end, it works super well. One of my dogs (Bob) just loves it. Albeit I can’t turn my back on him playing with it or he destroys it or the hose. I am sure most kids would love it too. Just press on the large pedal and water jets up into the air. Release the pedal and it stops.
As you can see from the animated gif images, there is considerable water leaking out from the mechanism because of the rough 3D-printed surfaces. I found that acceptable under the circumstances but one could probably reduce that if some time was spent on it.
The following diagram illustrates all the components and their relationships. Assembly is straight forward and no screws or fasteners are needed. I do recommend some garden hose washers (gaskets) as shown.
The water pressure from the hose will push the pedal up and then an pressure down on the pedal releases the flow of water up and out the fountain head. The following images try to illustrate that.
The main body prints standing on end with print support incorporated as show below.
The floating female hose connector might bind a little and needs to be coerced into free rotation as illustrated below.
I am now posting all of my new designs on Thangs.com and plan to continue to do so for the foreseeable future. Some of my older designs may not have been migrated over yet so if they are not available on Thangs.com please check on Thingiverse.
Use, Licensing, Comments and Feedback
My primary distribution site for my design files is Thangs.com. Thangs.com is, in my opinion, leading the way in promoting designers and competition amongst designers which in turn fuels the growth of high-quality 3d printable designs for the benefit of our entire community. However, as a result, some of my designs are only available for free for 1 week from when first posted, so please download them when you see a new file available that you are interested in. Also, please like and save to help me with the competitions.
I do not permit the use of my designs for commercial purposes (i.e. you can not sell my design(s) or products printed from my design(s)) without first acquiring a commercial license from me. On Thangs.com I offer membership accounts for access to all my design files as well as a membership for commercial licensing which allows subscribers to sell printed products using my designs.
I welcome comments and feedback as we as requests for customization of designs. I will do my best to accommodate those requests.
