PETG Temperature Testing Tower

I've begun experimenting with MatterHackers (MH) Build PETG as a possible replacement for nGen Colorfabb. nGen definitely has better quality control but MH comes close with similar durability and heat resistance at half the price. The jury is still out on what the best print settings are for MH Build PETG so I created this tower to see what temp creates the best aesthetics and/or best strength of adhesion between layers. Each section is 20mm tall for a 80mm tall tower. If you have Cura, it's a pretty simple process to create a post-processing GCode plugin that will change the temperature at a given height (this is usually pre-installed and called Tweak at Z). Anyways, not an exciting print but important to use so that your other prints can be useful. Welcome to provide any and all feedback!
