I've designed this simple temperature tower in order to test the best nozzle setting for PLA (185C - 215C).
Each temp cube is 20mm tall and it is recommended to print it with a 0.2mm layer height so you can set each temperature at every 100 layers in your slicer.
UPDATE: V1 has chamfers for better visualization of each temperature cube. Temperature numbers have also changed from engraved to embossed and walls and base now are 0.5mm thick.
Print with 1 shell, 0 top / bottom layers, vase mode.
Added the vase mode g-code if you want to print it right away instead of tweaking your slicer.
