Another temperature tower only I added I-beam cross sections to stiffen the tower so it doesn't sway at higher levels.

When I was printing the very nice tower from gaaZolee, I found that the tower flexed somewhat during printing especially at the higher levels / cooler temperatures. This led to an artificially worse print for the given temperature as the imprecision was partially caused by the moment arm of the horizontal force of the printer's drag along the top multiplied by the height. The solution is to increase the size and girth of the tower, but that opposes gaaZolee's original purpose was a quickly printed tower that tests for the correct temperature. Since I-beams stiffen beams with a minimal amount of material, I decided to create a wider, stiffer tower by using I-beams. The trick was how to do this without defeating all the detailed torture tests gaaZolee put in the original design. Secondly, the added re-enforcement needed to repeat on stacked layers to retain the benefit of the I-beam all the way up. I attempted this by adding a cross beam between the cylindrical hole and also by extending the side of the bridging with no gap. In order to control the temperature for each level, follow directions and links given by gaaZolee. I used the Macro function in Cura's "Extensions->Post Processing -> Modify G-Code" as shown below to set the temperature for each level. Note that the spacing on each level is the same as gaaZolee's.
Print Settings
Printer Brand: Monoprice (Wanhao rebrand)
Printer: Maker Ultimate
**Rafts:** Doesn't Matter
Supports: Doesn't Matter
**Resolution:** 0.2
Infill: 15%
**Filament:** Prusament PLA+ Grey
Notes:
Use on any new material to determine the ideal temperature.
I've used it with ABS, PLA, & PLA+ successsfully. For ABS, I had an ABS slurry on the glass platform. The platform was at 58C.
How I Designed This ===================
My additions in orange.
Setting up scripts to adjust the temperature for each level in Cura
Choose "ChangeAtZ" and create a script for each level.
Once done adding all the temperature changes at each Z location, choose close and slice the design. The scripts will be added into your g-code by Cura
