So I designed this little one way valve. See I needed a means to remove excess out of the bottom area of my auto pots. This is during the first bit when they a growing roots and not able to self water yet.

So I like to remove the excess that some times accumulates under the pot. Most hand pumps that you buy are really over kill. 

So I plopped in front of my computer and designed a simple little one way valve.  Printed it and voila a handy little pump.
