Vivosun Hydroponic Cap

I recently purchased a cheap Vivosun hydroponic vertical growing system from Amazon with 36 holes for plants. Everything is pre-cut which is a nice time saver but for some reason they've chosen to make all their holes square. And sometimes I don't have 36 plants to fill every hole. AND you dont want to leave your hydroponic system open to the environment if you can help it.

So I whipped up a little plug to close any holes I wasn't using in the pipes, nothing fancy or sophisticated. But it fits fairly tightly and has a nice edge to get a good grip to remove. I wish it would adhere to the pipe shape a little more cleanly and be more flush but maybe that's for a future iteration.

Print flat side down (you'll have to flip it in your slicer.)
I'm currently printing at .20 mm with 5% infill with PLA
