Tollerance tester for 3d Printer

Not having yet clear the minimum tolerances of my printer, I created this simple tool to perform a quick test.The tool tests tolerances from 0.2 to 0.4 mm.Added two more versions;The "bis" has the same dimensions but with the addition of a bevel on the corners at the base of each element, this to prevent the first layer (in which it is often printed at 120% of width), can compromise the test:The v2 has other dimensions, wider tolerances and a different section.The handling of the blocks of the three versions can be facilitated by using a 6mm socket wrench.Added v2 lighter
