Washer for 1 & 2 Liter Bottles for use with Self Watering Stick For Plants

thingiverse

I designed this washer specifically for use with the Self Watering Stick For Plants (https://www.thingiverse.com/thing:3534937). Initially, I encountered an issue with air leaking through the bottle threads, causing water to drain rapidly from the 1 liter and 2 liter bottles that it was intended to work with. After experimenting with Teflon tape, which provided a temporary solution, I found that it required reapplication every time the bottle needed refilling. To address this problem, I created a washer that can be manufactured using TPU, ensuring a secure seal similar to a standard washer.
