This is a desktop water fountain I made after being inspired by PrinterJay's, Table Fountain on Thingiverse. I wanted a fountain that would spin so I started making my own. I borrowed the basic design idea and the waterslides from his design. (Check out his design!). Other than the waterslides, the rest of it was made from scratch.
Note: When turning it on or off, a little bit of water can (most likely will) spill over the side on both models. To prevent this the outside walls of the Cup Top files can be raised.
Normal Size: 104mm x 104mm x ~190mm
Large Size:167.5mm x 167.5mm x ~265mm
I use a different pump than his because the one he's listed isn't sold in the US. Here is the one I use:

Check out the print settings and post-print sections to make this. You will also need superglue (I used CA glue), a standard skateboard bearing (8mm core, 22mm X 7mm), and hot glue or similar to plug a hole - see post-print section.
I made mine in PLA plastic but had to use a lot of glue to make the prints watertight. Something that might help is to print in ABS plastic and then acetone vapor treat the parts to seal the prints. I have not tried this.
Update: If a lot of water is spilling out, try increasing the flow rate of the water pump by one or two notches.
You know your printer best, these are my recommendations. Just keep in mind that the final print must be waterproof.
For the Normal Size:
Water Spiral: 0.2mm, good to high airflow/cooling, 100% infill. Remove support ring from
bottom after it's printed – holes are there to stick in needle nose pliers to help remove it.
Stem Cone and Spacer: 0.2mm, good to high airflow/cooling, 100% infill. The square
tower is there so that the stem layers can cool down before the next layer - prevents
messy layers; can be removed if your printer can print very slowly with high amounts
cooling pointed at the print.
Cup Bottom/Top: 0.2-0.25mm, 2 or 3 surface layers, infill can be custom (~15-25%). 4
perimeters or more unless you want to vibrate your machine apart for a hour or two.
For the Large Size:
Water Spiral: 0.2mm or 0.25mm, good airflow/cooling, 60-100% infill. Remove support
ring from bottom after it's printed – holes are there to stick in needle nose pliers to help
remove it.
Stem Cone and Spacer: 0.25mm, good airflow/cooling, 100% infill. The square tower is
there so that the stem layers can cool down before the next layer - prevents messy
layers; can be removed if your printer can print very slowly with high amounts cooling
pointed at the print.
Cup Bottom/Top: 0.2-0.25mm, 2 or 3 surface layers, infill can be custom (~15-25%).
Assembling and Gluing
Clean any strings or defects from printing. Do not use drops of superglue, place a continuous line of super glue so that the pieces will be watertight.
Note: FDM 3D printers might have trouble making a watertight base. If needed, be sure to seal the inside of the cup or top before gluing the fountain pieces together. I highly recommend sealing the interior walls of the cups and inside floor of the top cone (the area shown in picture below).
Spinning Spiral:
Take the skateboard bearing and insert it into the water spiral. Use superglue or hot glue around the outside of the bearing if the fit is loose.
Insert the smaller end of the stem into bottom of the bearing. Again, use glue if needed.
Looking at the top of the spiral, add superglue to the core of the bearing and on the small circle of plastic in the center of the bearing (that plastic is the stem). Center the spacer (raised-side down, flat-side up) on to the glue and hold until it stays in place. See picture.
Gently spin the spiral to prevent any glue drops from ceasing the bearing.
Looking at the top of the spiral, add superglue around the top of the outside wall where the cone will be touching. Place the cone on top and hold until glue sets.
Cup:
Set the pump to the lowest flow rate (Can adjust it higher later if water is spilling out). Place and secure the pump so that the outlet is in the center of the Bottom Cup.
Route the wire through the cutout and superglue in place. The wire should not be taller than the edge of the Bottom Cup.
Place superglue around the edge and place the Top Cup on top, flat-side down. It should be flush.
Use the hot glue or something waterproof to seal the wire cutout so water doesn't leak out.
Cup and Spiral:
Slide the Stem onto the 8.5mm water pump nozzle. If needed, add glue to the outside of the nozzle for a better water seal.
Add water to the base. Stop when water spills over into the Cup Top. Start the fountain, then add water additional water if needed.
