This is just another test print to check 

1. Tolerances

The model consists of four cutouts that can fit one Euro cent coin. The smallest has a diameter of 16.25 mm (the exact diameter of one cent)

The larger ones increase the diameter by 0.1 mm each. Just take a cent and see how snug it fits and if you can still turn it.

2. Dimensional accuracy

The dimensions of the model are 100 mm x 20mm x 3mm. With that you can check the dimensional accuracy of your printer by simply measuring the print.

I have used this part to validate my calibration and can now press one cent in the smallest cutout with some force, while still being able to slightly spin it in the others.

The relive cut on the left side of the model is to get seams out of the way for more accurate measurements.

Let me know if this model was of any use for you.
