This is a simple print used to test non-thru holes in prints. This tests your printer's ability to print:

-Small hole depths (1mm and 0.5 mm) -Small holes (1.55 mm holes and up) -Small wall thicknesses (1mm & 2mm)

For dimensions of the part, see the attached drawing (in the images section).

The septagon (also known as a heptagon) in the corner is used to orient the print with the drawing.
