Aeration tube for potted plants in soil

This device help me grow my tomatoes in the pots and may help you if you are using plastic pots for this purpose. 

Main advantages:

• keeps the roots breathing
• driving away CO2
• normalizes moisture across layers
• small holes does not allow soil or other particles to clog the tube
• + includes a plug when you need to keep it closed so nothing falls inside

Can be printed in PLA, 0.2mm works completely fine, around 10g of plastic each.

Watch for stability and vibration, speed better be reduced to 50mm/s.

Length can be reduced by compressing in slicer. 

But please let me know if you'll need other lengths, I will update the model.
