Dear beer friends
First, sorry for my Google translator - English.
Print the handle very strong and with 3 outer layers so he does not break. 0.2mm per layer.
A post-treatment with the hot air blower (very short) can not hurt either. To glue the layers even better
With: sketch-up - file
PLEASE: let me know, if you create a remix (other size of cans, other variants .. etc.). it would interest me!
and have fun !! Cheers from Switzerland
