Inspired by Mike's newer two-propeller wind-up boat with its more powerful spring, I decided to make a stronger spring for his original boat v5. I made it over-sized, so it needs to be pre-loaded (partially wound-up) when you install it. It runs significantly longer and with more power than the original spring.

Printing

I recommend printing this in ASA or ABS, which are more resilient than PLA. PLA makes a stronger spring but it's brittle and might not last as long. PETG is softer so it isn't great for springs but it would probably work in a pinch.
