The multi version is not the prettiest one, since the text only one layer.
I tried with ironing default settings, it was not perfect, slightly more flow needed, but feels much better then without, imho.
Please add a1 mini also for the printing profile, it is missing.
The multi versions text is 5 layers thick. Yeah each printer will need slightly different ironing settings, after running a calibration, the default turned out to work best for me but may be different for you. I'll adjust the print profile to include the A1 mini.
To be honest, I'm not sure. It was designed for EU carts. I've checked the diameter of the euro compared to Canadian coins and they don't seem to match up so probably not. The print only takes around 10 minutes so you could print it and give it a go.
