About this 3D model

This is a simple "net cup" for seedlings or cutlings grown in Eazy Plugs that are going to be transfered to a hydroponics system such as DWC. I assume it works just as well for rockwool cubes. The photo shows the previous iteration, in the STL the amount of plastic surrounding the grow cube has been reduced further to allow more space for roots. They fit a circular 65mm hole.
