Made this temp tower to find the optimal print temp for layer adhesion with PETG, but I added a stringing test tower in addition to the 3 boxes per layer. Each box is a different thickness, 1mm, 2mm, 3mm. This is to check wall strength per temp as well.

Trying to solve the delamination issues I'm facing with my PETG on the Ender 5 Plus.

The simple version prints faster, as it is just one single 3mm wall tower, no string testing, with a 1mm nozzle in mind. (You can print with different nozzles, the 1mm nozzle will just make 3 passes.)

Added the "3 walls" version for those using the standard 0.4 mm nozzle, the walls of the simple tower are 1.2mm thick, hence, 3 standard width perimeters per layer.

Added the "2 walls" version for those using the standard 0.4 mm nozzle, the walls of the simple tower are 0.8mm thick, hence, 2 standard width perimeters per layer.

TempDesc240-215 Is 3mm thick walls, temps starting at 240 (bottom) to 215 (top) in 5 degree increments (Descending temp, ascending height).

Finally, I realized that the single towers each still say 3mm on the side near the top, even though they aren't, but I can't be bothered to fix it.

Hope that others find it useful as well.
