Recommended print settings with a .4 mm nozzle
- Layer Hight: .150 ~.160 mm, depending on motors and gearing
- 3 perimeters or shells (1.2 ~ 1.5 mm)
- 8 bottom layers (1.2 ~ 1.3 mm)
- 8 top layers (1.2 ~ 1.3 mm)
- Infill 15%~20%, depending on infill type
Additional items needed for assembly
- 3 O-Rings of suitable size
1- Insert the three O-Rings in the corresponding grooves at the base of the cork.
2- Fill the used wine bottle with water.
3- Seal the wine bottle with the 3D printed cork.
4 - Dig an appropriate size and depth hole in the dirt next to the plant. The hole should be deep enough to allow the bottle to be in the dirt all the way to its shoulders.
5- Quickly invert the wine bottle and insert it in the hole. Make sure it is deep enough to be stable on its own.
Note: The size of the hole in the cork is calibrated to release water over a period of 3 to 5 days. This was done using my printer. Depending on the calibration of your printer, the actual size of the hole in the parts you print may vary. Some experimentation may be necessary to get the desired flow rate.
It is easy to bore out a slightly larger hole in the cork with a small bit. I had good success with the ~ .4 mm bits commonly sold to clean out printer nozzle. It is also possible to use a hot acupuncture needle.
Keep in mind that a very small increase in the diameter of the hole will result in a much faster flow rate.
