lost my calibration card

[fontoon 0]

I lost the small calibration card that looks like a business card for my Ultimaker 3.  I was thinking of using metal calibration shims, but I don't know the thickness.  Can someone tell me the thickness, or an adequate substitution.

A normal sheet of copy paper will do fine.

Originally I also used a piece of plain paper, but now I just do it visually: I print a border of 15cm x 15cm, one layer thick, with a skirt of 10 lines, and then adjust on the fly while it is printing this skirt. This works well for my UM2; I don't know if this is recommended for later printers like UM3 or 5.

I'm guessing that the auto leveling on UM3 and s5 will be a problem for the "on the fly" style adjustments.

Thank you guys for the feedback.
