Prevents roots from clogging and overflowing draining cascading pipes.



This entirely optional 3D-printed part can be used to keep long roots away from the inflow of the cascading pipes that drain the water from the growing pipe. This makes it less likely that the roots clog the system and the water overflows instead of draining.

Bill of materials

  • Food-safe 3D printing filament

Required tools

  • 3D Printer

  • PC running OpenSCAD.

  • PC running a slicing program suitable for your 3D printer, such as Slic3r.


  • Download the following OpenSCAD models:

  • Alternatively, if you are familiar with git and have it installed, clone the entire Project Springtime website from here and look for the .scad files in content/parts/overflowguard-1/cad.

  • In OpenSCAD, open each .scad file at a time and select "Design/Render (F6)".

  • In OpenSCAD, export each file as STL.

  • In your slicer, place the previously exported STL file. We suggest you slice and then print one file at a time.

  • In your slicer, you can probably use default parameters for your printer. (You know your printer better than we do.)

  • In your slicer, export the G-Code and print the G-Code with your 3D printer.
