Calibration Block for FlashForge Creator Pro

Created this balance block after seeing it a video for aligning the dual head extruder nozzles on a FlashForge Creator Pro. When I contacted FlashForge they told me that tool was not for sale so I decided to make my own and it works great. Print with PLA or ABS at 100% infill. This to make aligning the heads after disassembly a breeze. Hope you like it.
