Ultimate clearance calibration test

This is the ultimate calibration test to print to understand how much clearance you must leave between two parts to not melt them in a whole object.
Print it and press the pins in descending order (from lower right, going left, then middle right going left, at last first line going left). The last pin you can detach (without a hammer :) is the one identifying the minimum space you must leave between objects in your designs to not print a whole block.

The clearance of the pins are as follow:
(0.2mm) (0.3mm) (0.4mm)
(0.5mm) (0.6mm) (0.7mm) (0.8mm)
(0.9mm) (1.0mm) (1,1mm)
