Nuclear Cooling Tower Pen Holder

Update: I recommend printing the 126mm tall model. The wall thickness of the 100mm tall model seemed to create some weird artifacts in my testing. 

A neat little pen holder, make-up brush holder, paintbrush holder, smaller-holder-things-holder, or just about whatever you can fit in (and retrieve). There are two files, one for a 100mm tall model, and one for 126mm tall.

I was inspired by the Cooling Tower Pen Holder by @Charles_Lambe_238563 and his model of the Didcot B cooling tower, but I wanted a unique one modeled after the plant I work at, Grand Gulf Nuclear Station. I added the inspection walkways to mine to make it unique, and I did model it from scratch so it's not a remix, but Charles deserves credit for the inspiration.

Warning: If you print this in PLA Silk, wait for the build plate to cool. The top of the support section is not very strong, especially in silk. 

You may also need to lower your speed settings for higher-speed printers. I started getting artifacts at the wide part of the base. 

Supports should not be required if your printer can do even small bridges. I made sure the walkways had an angle underneath. 

Print Setting Recommendations:
Infill: 10-20% (Doesn't really matter)
Precise Wall and/or Arachne settings
I recommend that any Aux Fans should be turned off until after the pillar/support section has been printed and a few layers past that.

If your printer is not well calibrated or doesn't have great cooling, I also advise that you slow down the printspeed around the pillar/support sections and near the top.
