Just printed it (again) 
. Same settings in Cura.
Printing time decreased and the line/spaces come out nice this time.
Is it correct that the scale isn’t a Vernier-scale anymore? The “zero” spacing at the end matches the 10 cm exactly. Or am I missing something? As a financial analyst I’m more of a debit/credit kinda guy.
I if simply mirror the STL-file, can I use that part for the other end of the tape measure?
