Self-watering planter water level indicator
Description
This is a water level indicator for the [self-watering planter](https://www.thingiverse.com/thing:903411) from [Parallel Goods](https://parallelgoods.co/). The principle of operation is that a floater inside the reservoir pushes an indicator ring out of the reservoir refill tube when water is added. Once this indicator has sunk below the rim of the refill tube, it is time to refill the pot! Refill can be done through the indicator ring. Update 2019-05-18: The indicator, stabilizer and floater have been updated to decrease risk of friction. A tool has been added which is useful when adjusting the orientation of the stabilizer inside the refill tube.
