Greenhouse for Pot Growing (remix)

My wife asked for something to prevent the rods from tilting to a side - to give them more stability.
So I found ewaps https://www.thingiverse.com/thing:2262316 which I instantly loved. He has detailed instructions and even a video with his thing.

But I liked to remix it to make it fit to my needs:

TOP

My top has three holes for the ropes. I think they can be fixed easier that way. There is no hole to inject the hot-glue. You can add a small portion of glue to the rod directly and stick it in quickly (mark the position before so that it is leveled once it is fixed).

HOOK and BUCKLE

I made a bigger hook. My pots are made of potters clay and the rim is thicker.

I used paracord instead of flexible plant tie. That´s why I needed some kind of tensioner. I used the third version of the „Quick Kont Tent Wind Rope Buckle Clam“ which I added as a stl-file here. Dnpro made a V4 meanwhile - maybe you like to try this: https://www.thingiverse.com/thing:2046552

FOIL

My pots do have a diameter of about 36 cm and I measured a length of 160 cm from the top to the rim of the pot.
I used this simplified formula (cone, not truncated cone) to calculate the top-angle in degrees:

a = D/L * 180deg

a = top-angel
D = diameter of the pot
L = length of the side

You have to add at least 20 cm in length for overlapping top and bottom.

My foil was 150 cm wide and cutting of a peace of 180 cm and then making two parts along the diagonal line made it for me - see the attached picture.

UPDATE: I added a top for a different type of rod - straight and with 12 mm diameter. I also put Ewaps hook here. This one is very small and fits to the tiny rim of the plastic-plates underneath my pots.
