Kratky Plant holder for 2 inch net pods fits 2.5 inch hole

I wanted a 3D print to hold up plants in a 5 gallon bucket.  I started with a base that I can insert a 2" net pod and then I created inserts that hold up the plant a few inches up. The base is in two pieces that snap together after you insert the netpod. The insert also locks the system together. Different inserts are provided depending on on how big the plant might get. I include a 7, 10, 15, 20, 30 and full size (about 33.5mm) insert. The inserts can be removed and replaced as the plant grows.

To be honest I started this from scratch with just an idea after setting up my first bucket. The results looks good and works but I find I made it a bit bulky and I wish I had made it thinner. I will stick with this version for now and honestly I love 3d printing as much as my gardening so a bit more filament does not bother me. 

The one improvement might be to put tabs on the insert to make it easier to remove. The insert snaps to the columns of the base and holds very well. Tabs might help open up the arms to help slip the insert up. It'ss not too hard with your fingers or nails you can get under the pull the two arms up.

When placing the insert you should rotate it by 90 degrees to the two base pieces that locks the holder together. It won't budge when installed that way. 

To print you will only find one piece for the base and one for the insert. Print two of each and snap them together.

To install it simply drill a 2.5" hole on top of your bucket and the base should snap right in. 

I am including a step file for the design in case someone what's to make some improvements.
