Swamp Plant sub-soil water tank

thingiverse

I have no idea whether anyone will need that thing, because its use is quite specific. I have a few pinguicula plants (or butterworts according to Wikipedia). They are carnivorous swamp plants (very useful against fruit flies) and require constantly wet swamp soil to grow. Since they don't root very deep, I planted them in cornflakes bowls, which means the surface area is relatively large and it also doesn't allow for a lot of water storage. To solve this problem, I've designed this sub-soil water tank. Edit 01/21: I added an adaptor ("Wassertank_Fk_Verl_Stopfen") to the water inlet to increase its height, so that the plants don't cover up the opening. I also added a floating water indicator ("Zylinder_Schwimmer" + "Zylinder_Schwimmer_oben") to help in determining when the water tank is filled. Main features: - Water tank to be dug beneath the soil - Small slits in its sides allow for water to flow into the soil - A funnel on top allows for easy refilling - A cap prevents dirt from falling into the tank - I'd recommend putting gravel on the bottom of the bowl for easier water spreading Printing Options: - I tested it with PLA so far - Use no supports on the inside; the "ceiling" is held by bridging
