Calibration

Mainly designed to test wall thickness and flow to achieve dimensional accuracy. Currently my printer over-extrudes by a good bit. I hope to adjust settings to fix this and get more accurate parts instead of parts that are about .4-.5mm to large on all edges.
Dimensions:
Widest wall - 3mm x 36mm x 4mm
Middle wall - 2mm x 36mm x 5mm
Thin wall - 1mm x 36mm x 6mm
Circle - 12mm OD, 10mm ID, 2mm wall thickness
Cube - 11.67 mm on all sides
Base of part - 40mm x 40mm x 2mm

All Dimensions are in X, Y, Z
