DescriptionKeeps small sections of the growing cube material from topping over in the germination tray
This is an entirely optional part. It is convenient if you germinate small batches of seeds, and break the cube material into relatively small pieces. These small pieces tend to topple over in the germination tray, drowning the plant.
This part, in some variations, prevents the growing cube(s) from toppling over.

Download one of the OpenSCAD models, depending on the size and shape you want:
Alternatively, if you are more technically inclined and have
gitinstalled, clone the entire Project Springtime website from here and look for the .scad files in
In OpenSCAD, open this .scad file you want and and select “Design/Render (F6)”.
In OpenSCAD, export as STL.
In your slicer, place the previously exported STL file.
In your slicer, you can probably use default parameters for your printer. This is not a part that has to be printed particularly precisely. However, you may not want to use the fastest printing mode, as some aspects of the part are fairly thin, and printing fast may not add enough material to make them sturdy enough.
In your slicer, export the G-Code and print the G-Code.
