Seedling/Transplant Pots and Trays

This is a set of different pots and trays for growing seedling or transplants in.
I have 3 sizes of pot; 42mm, 58mm, and 76mm. They are all made with a removable bottom so when it comes time to remove the plant it's easier to just push it up from the bottom without disturbing the roots.
There is also a bottom tray to hold water (would of course need to be waterproofed with epoxy or other) and there is a grid for each size which holds the pots in place and keeps them from tipping.
I printed these from PETG, of course, as they will be constantly wet and I printed different colors of pots so I could separate different types of plants by color, but it's all up to you of course.
No supports needed. When I printed the pots (or cells) and the cell bottoms, I printed them upside down, with the bottom nested inside of the pot so I could print them all at one time.
Besides the 3 sizes of pots/cells and the matching bottoms, I have a tray and grid for different size printers.
The standard tray is 233x233mm. With this tray it can hold 5x5 (42mm), 4x4 (58mm), or 3x3 (76mm) and I have the matching grid for each of these included in the models.
If you have a smaller print bed (like a Prusa) you can still use the same cells, but you'll need to print the 233x186mm tray. For this tray the corresponding numbers are 5x4 (42mm), 4x3 (58mm), or 3x3 (76mm) and I have the matching grid for each of these as well.
