I design this to test the best settings for new filaments with minimal material to save time and cost.
You can run this as a torture test too. (so the name fence of death)
Start from higher temperature then try lower the temperature every 5-10 degrees to see the results. You can adjust other settings for retraction, speed, etc. But I recommend playing with temperature first.
I found out the best temp. for my new PLA filament was in fact 175 degree to give the finest detail.
Print with a small brim for stability.
