Watering stake for all your houseplants! printed in PLA it uses any glass bottle, just fill the bottle up and drop your insert in the stake and stick it in your soil. I printed mine on a P1S with Bambu labs PLA and all the tolerances work nicely, if you leave all the holes open it takes about 30 mins for a 16oz bottle to drain, if you want you can cover as many of the holes as you like on the bottom of the insert (with tape of glue) before you drop it in the stake and slow the drip even more.
