Thermal Expansion Calibration / Dimensional Compensation

This is a very simple test file that I am using to calibrate my printer to get perfect dimensional accuracy with any filament roll. I usually print one of these before I use any filament roll and then compensate for its thermal expansion. I am then always getting perfect openings and threads with that particular filament type and color, minimizing any post-processing time.

The file is designed so as to minimize filament use. I suggest printing it with three layers/walls, with 10% infill. It s
