3D Printed Bong - Expansion pack

This is the 3D Printed Bong Expansion pack!
This pack includes some modules which work with any other part of the 3D printed bong (check it out in my designs!).
All modules have been designed to work properly and efficiently, but some are harder to print (read below), and most have a overhang toward the top which can be easily accomplished with a good cooling system (it is a 60 degree angle).
The pieces included and the difficulty of printing are:
-Svelte Neck (Diameter=46mm, Height=140mm): this module is relatively easy to print, equal in size and function to the Straight Neck (from the Basic Pack), but shaped like a handle with a diameter of 24mm, to have a nice firm grip on your bong.
-Pillars Neck (Diameter=46mm, Height=140mm): this module is relatively easy to print, adds a cool look and slightly cools down the smoke by exposing it to more surfaces, support from build plate is suggested to print the bottom insides well.
-HexaCube Neck (Diameter=46mm, Height=140mm): this module looks quite menacing to print without supports for the hexagonal cage, but it is quite easy actually (they are 60 degree overhangs), support from build plate is suggested to print the bottom insides well. This was a request from a friend to create something with a cube and future-looking, without losing any airflow.
-Spiral Neck (Diameter=46mm, Height=140mm): this module is amongst the hardest to print of the pack because of the constant slight overhang of the spirals, but is still easily achievable. It makes the Bong look dynamic and beautiful, while also cooling the smoke. Support from build plate is suggested to print the bottom insides well.
-Spiral Top (Diameter=53mm, Height=110mm): Just like the Straight Top (from the basic pack) but with a spiral pattern around it for better grip.
MANY MORE PIECES INCOMING!!!
NOTES:
-I am open to suggestions and especially requests. If you come up with a great design for a piece and want me to model it for you, just contact me here or through reddit at u/JaykdaBeast, and I'll do my best. Also if when requesting a piece, if you have already bought the Basic Pack, I will send the custom piece for free; if the piece is also clever and functional, I might even add it in future packs.
-The last pictures showcase pieces which are not included in this pack, but can be found in my shop.
-The pictures for the Spiral Neck have been sent to my by a friend, so they aren't as HD as the others: sorry for the inconvenience!
ATTENTION!
-This pack is an extension of the Basic Pack. Buying this without having the main pieces for your bong wouldn't be a great idea.
The last pictures show how these pieces would look if combined with the basic pack.
-Just like the basic pack, I highly recommend printing these parts with PETG, as it is food safe and does not let water stick to it, making it easier to clean (PLA will start collecting bacteria after a while and has an unpleasant odour).

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 of the percolator is 100% water tight)
-Infill: although I suggest printing this with 100% infill, as it doesn't add much time, it is not necessary (if you use the wall and top/bottom thickness I specified)
-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 slight overhangs which need to come out well for the threads (45°)
-Supports: from the build plate if there are more than one tubes, otherwise none
