A simple testprint consisting of simple joints with 5mm radius rod and a 5mm a 5.05mm a 5.1mm a 5.15 a 5.2 and a 5.3mm radius hole. This allows you to test the fitting tolernaces of a given printer and material and see how well different tolerances it together and how movable they are. The whole articel can be scaled up or down to test finer sets of tolerances in different size joints.
