Seedling Planter

I have been thinking about designing a reusable planter for starting seedlings for a while. So, I decided to try making something in Fusion 360. As you can see, the default size, on the left, is pretty small. I didn't think it would be terribly practical, so I tried scaling it in my slicer. That is where the other two prints come in. I printed the other two 200% and 300%. I think that 200% works best for smaller seeds, while 300% should work for things such as melons and other larger seeds.
This is not designed as a long term planter, but more as a starting point. The basket is meant to be planted with the seedling. I printed it with PLA, so it may, or may not be reusable. Time will tell.
I should also say that the tray hasn't been printed yet, so I can't offer any suggestions, except that you should scale it with the other components.

I designed the holder/planter to be the reusable part, since you can put a new basket into it. It also has some space inside that is meant to work
