Update 31.05.2019: This thing now has a big sister. You can find her here: https://www.thingiverse.com/thing:3665139 Update 30.07.2018: I recently fiddled with settings and discovered some key things. - You can print this airtight using 0.2 mm layer height with the extrusion multiplier set to 150%. - When printing in 0.1 mm layer height, the extrusion multiplier just needs to be increased to 130%. - When setting up post-processing for speed changes, choose 'change speed' instead of 'change print speed', as that caused failed prints for me. Also, I added gcode files (Marlin flavor) with 0.15 mm layer height that have the post-processing set up correctly and work flawlessly on my Ender 2 (Check out the pictures). They should work on any printer with a bed size at least as large as the Ender 2. They might just be printed off center. The files are all the same except for temperature settings. I made one for normal PLA, high-temperature PLA, and PETG. The values at the end of each name mean: nozzle temperature for the first layer, nozzle temperature for the rest, bed temperature. For my PETG (from Das Filament), it's 240°C for the first layer, 230°C for the rest, and 75°C for the bed. If you need different temperature settings, contact me. Cheers and happy printing! ------------------------------------------------------------------------------------------------------------------- I got inspired by those fancy plant watering balls that you can put into your flower pot to have a small and consistent water flow over time. So you can leave your plants unattended for some time. Feel free to modify or remake this. The only constraint you have when designing this is overhangs and a fixed outer diameter at the outlet of 9 mm (or less). This fixed diameter is needed to keep the water in and slowly drain it. For a stable print, you need to flip it around so the open side is touching the build plate.
