I found this and printed it, but the parts don't match the pictures. They should be updated to be consistent. The stackable design and syphon ideas are SUPERB! I ended up printing a liner mesh for the inside since my broccoli seeds always got jammed in between the bottom rails. I also think a simple bevel on the bottom would make stacking easier (the current design requires force and snapping to stack them closely). Still, it's been a great experience. I just used PLA. My theory is that the water rinses everything several times a day and the sprouts hardly touch the PLA anyway.

I'm would like to print it, but looks like the model of the container have a bottonlid in the file. I cant see how i would stack 2 containers...

I doubt that I will make this, as I don't have any printable food-ok materials and I don't want to use PLA for growing something inside, but I really like the whole idea. Just the idea of this and the looks is awesome, I really like it.

Hope to see more like this in the near future =)

If you're having issues with natural/transparent PLA, which generally seems to be considered food-safe, try one of the new PET filaments to be on the absolutely safe side. It would also be great if more manufacturers would offer stainless steel nozzles instead of the brass types. We have covered this in the FAQ on the project's page.

Hi Chron0,
Even if PET is considered food safe, I would doubt many of the Chinese manufacturers actually use food safe practices which would involve not using other chemicals around the filament and the filament preparation area. For all we know, the PET pellets chould be stored next to a container full of rat poison before or after it was extruded. I would also be concerned about making the item because of this possibility. Unfortunately using any kind of locallly made filament which might be more trustworthy is just too expensive. I don't really know why when you consider that plastic pellets can be bought for less than $2 per kilo in bulk but filament costs more than $20 per kilo.
