Dimensional Calibration Block

This test was designed to address some issues i have found with other tests i have seen. Many of which are to large (take to long to print), to general (test to many things at the same time), or to vague (do not properly reference all the critical variables needed to make them useful).

Block prints in under 10 minutes.
All relevant dimensions are documented in .pdf drawing.
Drawing is dual dimensioned (for those of you who insist on using the imperial units).
Evaluates internal and external accuracy.
Bottom is camferd to compensate to first layer over extrusion.
