Vivarium Water Feature

thingiverse

I'm setting up my very first vivarium to house poison dart frogs. It seems these frogs will want a stream or waterfall in their home. I don't really want a waterfall in my first viv so I'm going to make a stream. I've thrown together some really gross openscad source and am in the process of printing these parts in ABS with the intention of welding them together once finished. I'm hoping to get about a 2 degree fall to the stream. I plan to line it with glass pebbles or aquarium gravel. The tray in the pool should allow 3mm of water or so to build up so the frogs can take a dip without drowning.
