Summary

It is designed for 3D printer environment's quirkx research by itself.
Test pieces are two block femail block and male block.
After print conjunct it and measure distance of between bases.
This test piece has 9 poles and about 5mmx 5mm rectangle. And it has varied tolerance 0.2mm step thru 0.6 by 0.05mm as 4.4mm, 4.45mm, 4.5mm ... 4.8mm
Each poles length are varied as 10mm thru 1mm by 1mm step.
You can measure by caliper scale etc.
Picture of measurement case shows 3mm distance.
0: Tolerance less than 0.2mm
1: 0.25mm
2: 0.3mm
3: 0.35mm
4:
