Terrarium fountain waterfall

thingiverse

I needed a waterfall for my nano-terrarium with a false bottom drain.I used a tiny 12V pump to power it, but any pump that fits under it would probably work.https://www.aliexpress.com/item/1005005850115302.htmlIt was a pain trying to get the perfect flow. I ended up using a LM317 to adjust the voltage on the 12V pump lower, which worked better than trying to divert or squeeze the tube, and the pump is ultra quiet at around 3 volts. It may last longer going slower too? Who knows.https://www.aliexpress.com/item/32495099075.htmlI included a DXF of the plate I made for a 5 gallon aquarium in case anyone wants to make a false bottom to drain into.
