2.5gal Bucket Kratky Hydroponic Lids & Water Level Indicator. Multiple pot options

These are 2.5 gallon bucket tops for kratky style hydroponics. the design is similar to my original 40oz pots https://www.printables.com/model/897855-40oz-kratky-hydroponic-pot-with-water-level-indica. 

There are several lid options for net pots from 2in/50mm to 3in/80mm and one for 100mm plant pots that smaller plants come in at the store.

For the water level indicator drill a 3/8in/10mm hole near the bottom allowing enough room for the spacer. apply silicone(or sealer of choice) to the spacer and fitting. insert the fitting in the bucket and then put the spacer on the inside. Make sure to put the curved side of the spacer to the bucket. install and tighten down the first nut and then a second nut(optional) to make sure things stay tight. Once your sealer has cured you can install your tubing.

Use 1/4in id tubing of your choice. I like to use the stiffer tubing and heat it up to install for a water tight fit or you can use flexible tubing with a small zip tie as a hose clamp. The lid has a less tight fit for easy removal.

The water level fitting can print in the way it loads but will need a brim. no supports are needed. You have to rotate the lids 180 degrees.
