mendel spring design for soft PLA springs

thingiverse

This is an alternative design for mendel springs printed with soft PLA. Because the standard mendel springs printed with ABS break, if you squeeze them to much and loose their springiness, I tried to print them using soft PLA. But soft PLA is springy itself and thus the spring is not hard enough anymore. So I designed a soft PLA spring which is hard enough but very springy and doesn't break if you squeeze it to much. The first design was just as springy as the standard ones which were not satisfying when printed with soft PLA. But the mirrored ones are fantastic.
