A simple self watering planter with water indicator. 

some assembly required for the water indicator part. 
first you need a styrofoam. I bought some at Michaels, you probably can find it at hobby lobby or home depot. 
cut out your Styrofoam at least 55 mm long

but the width needs to be 10.5mm to fit the Styrofoam holder piece

then attach it to the foam holder piece

then assemble the rest of the indicator parts. the flag goes inside the top portion first 




then connect the foam holder at the end of the flag (you might need to sand the flag part to fit, it was kinda hard to do the tolerance with that brim getting added to the material, after that you can super glue it together)




and then insert this 3 piece to the tube. there should be a small locking grove that you just need to twist to lock (super glue is optional at this part).



should look like this

and Thats it!! you're all set

NOTE: the Cachepot (apparently that's the name of the container that goes inside the planter). the print profile on that has a slight 45° rotation, for less support. but how you print it, is up to you, i just preferred it this way.
