This is a simple holder designed for the Seedling Shell by wc23: https://www.printables.com/model/235200-seedling-shells
As far as plant pots go, I do find that model to be one of the best, however, the holder/support is rather resource and time-intensive. As such, I set out to make a simpler model that fits the seedling shells, but can be printed quicker and without supports.
The full model is split into 3, with custom connectors between each part. I've been able to print and connect them without needing any glue, a bit of force was needed to get the parts to clip together, but otherwise, it worked well.
Some notes:
The author remixed this model.
This is a remix of the holder for the shell. It's designed to be a lot simpler and cheaper to print (but be warned, it is not as strong as the original).
