The Lightning - Recycler bong

Hi everyone again!
Although its appearance may not be the same of a normal recycler, the functionality is all there: this design was to guarantee printability and also its obscure appearance might be what you're looking for.
But what is a recycler? The idea is to force the water into a "closed loop", forcing its motion thanks to the air inhaled by our lungs. The water rises to the entrance of the tiny side tube thanks to the bubbles caused by the thin slits on the percolator, and then slides back down in the main chamber through the tube. The advantage is that this way the water stays cooler and the smoke cycles around.
How it works:
Half of the base roughly must be filled with water: you can check if the amount is right by hitting it, but it is quite easy not to miss it. I suggest filling it halfway, and pull to check: If you don't feel water flowing through the outside small tube, it means there is not enough; if you see water running up the 14mm intake, there is too much water.
Splashing is also prevented thanks to the shape of the recycler, which bends twice not allowing for anything to come back up.
Note that this piece is 17cm tall: you don't have to pull too hard while using it. Also be careful while using a lighter not to burn your hair!
ATTENTION!
-I highly recommend using PETG for printing the piece, as it is food safe and water tight.
-I also recommend getting the 14mm ash catcher from my shop, as it is free and extends the recycler's lifetime a lot by eliminating strong bad smell.
-The recycler has a hole for 14mm sliders. A glass slider must be bought for this, as printing it and using it in plastic would be really hazardous. You can find them for cheap on amazon.

As I said, I highly recommend printing with PETG.
These settings are to ensure that the walls are completely solid, just like the bottom.
-Wall thickness: >1mm (So that the walls are filled with perimeters)
-Top/Bottom thickness: >1mm (So that the base is 100% water tight)
-Layer Height: 0.2 is the best for speed and final looks, but I'm pretty sure you could print with any layer height (have not tried).
-Cooling: yes (accordingly), as there are some overhangs which need to come out well (the pipes and the ice catcher)
-Supports: none
-Infill: I recommend above 30%, as the edge around the base has a small are with infill.
