  Added a test Lid for 5 Gallon Buckets. I used some 3D model buckets as reference because i dont have one at the moment. Maximum inner and outer diameter of the tested bucket models are below in the description.
  (will add a version without the support rods in the lid later)

  Changed the Lid for the IKEA Version to be a little bit more stable in the long run (made the Connections longer and a little thicker.
  Changed the Center Pipe Module Part 1 to have a bigger and stronger Ring for stability (still compatible with all Lid Versions)

I modified the lid sections and the module adapter so that no glue or bolts are needed anymore. I also adjusted the size to fit better on my bucket and added height-adjustable support pillars to make everything more stable.

it should work with most printer sizes. I tested Prusa Mk3s, Mk4s and Prusa XL.

The center module for the other Tower pieces should also work with most other Lids as long as ther is enough space for the ring.
 

The Bucket i use is IKEA PS FEJÖ 32cm

5 Gallon Version (I did not Print it):

I used two slightly different models, as you can see in the pictures above. The largest outer diameter was (31.5cm/12.4inch) and the smallest inner diameter was (28.9cm/11.37inch). Anything between the two should work.

5 Gallon Bucket Lid differences:

Version 1: max Outer wall/lip ~ (12.4 inch/315mm) 
                  max Inner wall/lip ~ (11.37 inch/289mm)

Version 2: max Outer wall/lip ~ 12 1/4 inch (311.15mm)
                  max Inner wall/lip 11 1/4 inch (285.75mm)

 Added a Hole for Water Level Indicator from 

I think the support rods arnt necessary in the Bucket version and could be too short.

If you test it please leave feedback so I can change or improve something if necessary. 
If you need other measurements let me know in the Comments i will try my best :).
Thanks
