This is a tiny kugel fountain that works just like the giant ones!
The fountain works by using a DC pump to create a hydraulic bearing that causes the billiard ball to float on a cushion of water with no resistance to movement.
There are 3 nozzles in the STL files. The static nozzle causes the ball to remain stationary, the roll nozzle causes the ball to roll, and the spin nozzle causes the ball to spin. Print all three to compare! Fun for the whole family!
The nozzle prints best at a fine layer height, the rest of the part are unaffected. Print everything with extra perimeters so it is watertight.
- Printed Reservior
- Printed lid
- Printed nozzle of your choice
- 12v DC pump
- Billiard cue or other 57.2mm ball
- 5v power source and connectors
The pump you are looking for is a:
"DC 12V 4.2W 240L/H Flow Rate Waterproof Brushless Pump"
There are 2 main variations of these common 240L/H pumps, the one you want to order has ridges on the side. Both will work, but the smooth sided kind would have to be glued in. (see photo above for what the pump looks like without the bracket it comes with)
- Thread the pump wires through the hole in the reservoir.
- Set the pump in the reservoir, aligning the posts with the ridges on the side of the pump, guiding the wires out as you do so.
- Heat the curved surface of the nozzle until the plastic is soft then press it against the ball until cool. (Not entirely necessary, but it makes the system more efficient)
- Press the nozzle onto the top outlet of the pump.
- Seal the hole the wires go through.
- Affix a connector to the end of the pump wires.
- Fill reservoir with water to the top of the pump (do not overfill)
- Set the lid onto the reservoir.
- Set the ball into the nozzle.
- Start er up!
The pump is a 12v pump, but running it off of 5v is more than adequate for this application and makes the fountain much quieter.
