Needed a replacement ground spike for my hoselink solar lights (this model https://www.hoselink.com.au/products/solar-path-light-motion-sensor?variant=19426050834528\)
Decided to model it in Fusion360 and adding it here in the hope it'll be useful for someone out there.
I'm limited by my printer otherwise it could be longer. It works fine as is though at 105 mm on the stake part
Print with standard supports and brim at 0.2 mm
