When I tested out the model and used it as a drain in the kitchen sink it was a bit small for the sink and even with the broken area it worked well.
TIP: some people say PLA and things that go in your mouth are not a good mix (this is not yet confirmed)

Step 1: 2 Part Kitchen Sink Drain Model As Printed by Thingiverse Model Author (not Me)
TIP: When choosing a model from thingiverse to test print make sure to read the description and author write up to know if you need to customize the print to get best results.
Step 2: Printing the Sturdy Base
The image shows the 3D print right when the fragile area was starting to print in a spiral fashion which was brittle and where the piece broke.
It might work better if it was sized larger. Thank you to the author of the model for posting and adding to my learning experience.
TIP: In KiSSlicer you can multiply your part by X to change the size by 90% or 110%
Step 3: Printing the Sides
TIP: When printing expect a few final models to break or get ruined and it is still ok. With this print as it required 2 STL files printing out a replacement would be even quicker than if it required printing both parts each time.
Step 4: A Final Fragile Print
TIP: Depending on your PLA, Z Height between nozzle and platform, and the nozzle temperature your print can be easy or very difficult to remove. Make sure to remove by only pulling on areas that are not fragile. A putty knife works well to remove items from the blue painters tape.
This object did not break during removal - it broke when showing it to other people who liked what they saw and did not know it was so fragile.
Step 5: Good Looking But Fragile
When printing this object I found that some of the cool model parts like the ball at the top might have made the model more fragile due to the relative width and height of each individual part although that is not where it broke.
TIP: When printing pillars using a spiral print method consider the thickness of the spirals and how rigid or flexible they need to be based on their function and location.
