yeah thats what i though. I wanted to make a print-n-go zheng3 style penny balista that used some sort of printed spring, just for swankiness value.
Probably it's limit here in PLA for it's diameter/number of ribs etc :-
However I will soon print one out in the flexible Arnitel Eco 1.75mm which is being delivered soon. I will post pictures when printed. I suspect it will be really flexible but not very good for direct drive applications.
I have also made one out of metal for a much tougher requirement.
